area of cube

Let us find out area of cube.

Cube of a number is that number raised to the power three

The cube is also said to be as a regular hexahedron & cube is one of the five Platonic solids.

Find the lateral area of cube with side length 4 meter.

Solution

The lateral area of a cube = 4a² square units

Given, a = 4

So, the lateral area of the given cube = 4 * 4²

= 4* 4* 4

= 64

The lateral area of the given cube is 64 square meter.

Find the lateral area of cube whose side length is 3 feet.

Solution

The lateral area of a cube = 4a² square units

Given, a = 3

So, the lateral area of the given cube = 4 * 3²

= 4 * 3 * 3

= 36

The lateral area of the given cube is 36 square feet.

Surds

Hi Friends!!!

Let us learn how to do surds?

Surds are numbers left in 'conservativist base work' or 'square root form' (or 'solid structure work' etc). An reasonless root of a noetic numerate is famed as a surd. They are therefore irrational numbers They are therefore incoherent drawing. The intellect we lose them as surds is because in quantitative spring they would go on forever and so this is a real clumsy way of composition them.

Let us learn how to add surds ( 5 +√32 - ( 12 + √50
Solution : First we simplify the surds √32 and √50
√50 = √25x2 = 5√2
Now (5 + √32) – (12+ √50)
= 5 + 4√2 –(12 +5√2)
= 5 + 4√2 -12-5√2 Here the surd √2 is common term so like surds
= 5 -12 + √2( 4-5)
= -7 - √2

Einstein's concept of non-euclidean

Welcome to math tutor online for free,
Einstein came along and discovered
that these non-Euclidean geometries were just the thing to describe
the real-world interactions of objects with mass - that is, to
describe gravity. examples on math forum; This is a case where the mathematical system was
invented with no consideration of the real world (and therefore no
faith element), but it turned out that this system does appear to
describe the real world.

The experiments to show that Einstein's theory of general relativity
do describe the real world better than any other mathematical system
are very tricky; it is still possible that another system would do
better. We can be absolutely sure that the results of general
relativity theory follow from its assumptions; the only question is
whether or not those assumptions match the way the real world is.

law of trichotomy

Welcome to online math forum,
The law of trichotomy still isn't covered. It can be split into two parts: at most one of the three cases can occur, and at least one of the three cases occurs. more examples on math forum; The first can be stated as an axiom of addition as

It is not the case that x = x + y.

And that says it is not the case that x > x. The other half requires the axiom

For each x and y, either x = y or there is some z such that x + z = y, or there is some z such that x = y + z.

With these axioms, all the properties of magnitudes needed in the first few books of the Elements can be proved. For instance, we can prove

If 2x = 2y, then x = y.

Euclid's square theory

Welcome to math tutoring,
The only figure defined here that Euclid actually uses is the square. The other names of figures may have been common at the time of Euclid's writing, or they may have been left over from earlier authors' versions of the Elements. Euclid makes much use of parallelogram, or parallelogrammic area, which he does not define, but clearly means quadrilateral with parallel opposite sides. Parallelograms include rhombi and rhomboids as special cases. get more examples on help in math; And rather than oblong, he uses rectangle, or rectangular parallelogram, which includes both squares and oblongs.

Squares and oblongs are defined to be "right-angled." Of course, that is intended to mean that all four angles are right angles. Sometimes Euclid's definitions are too brief, but the intended meaning can easily be determined from the way the definitions are used. In particular, proposition I.46 constructs a square, and all four angles are constructed to be right, not just one of them. read more on free math tutoring.

Online trigonometry help

Hi Friends!!! let us learn about Free trigonometry help

Online trigonometry is a branch of mathematics that studies triangles, particularly good triangles. Trigonometry deals with relationships between the sides and the angles of triangles, and with trigonometric functions, which depict those relationships and angles in mass, and the event of waves specified as measure and short waves.

Trigonometry homework is ordinarily taught in third hand schools either as a severalise education or as try of a precalculus layer. It has applications in both unalloyed math and applied science, where it is intrinsic in more branches of study and discipline. A grow of trigonometry, called spherical trigonometry, studies triangles on spheres, and is essential in astronomy and piloting.

Figures and there boundry

Welcome to free math tutoring online,

The definition of figure needs to be fleshed out. In order to be a figure, a region must be bounded, that is, held in by a boundary. For instance, an infinite plane is unbounded, so it is not intended to be a figure. Neither is the region between two parallel lines even though that region has the two parallel lines as its extremities.

Other figures may be considered if other ambient spaces are allowed, although Euclid only uses plane and solid figures. online math forum; For a one-dimensional example, a line segment could be considered to be a figure in an infinite line with its endpoints as its boundary. Also, a hemisphere could be considered to be a figure on the surface of a sphere with the equator as its boundary. read more on math forum.

Plane surface elements

Welcome to free math help,

We see now that a plane surface, usually abbreviated to the single word "plane," is a kind of surface. Perhaps the remainder of the statement is a definition of content, but, if so, some words are missing.

One interpretation often given is that if a plane surface contains two points, then it contains the line connecting the two points. If that were the meaning, then it would be just as well to make that the explicit definition or to make it a postulate. examples on online math tutors ; But that does not seem to be Euclid's intent. His proposition XI.7 has a detailed proof that the line joining two points on two parallel lines lies in the plane of the two parallel lines. No proof at all would be necessary if that line were by definition or by postulate contained in a plane that contained its ends.

Note that a plane surface may be infinite, but needn't be infinite. It can be a square, a circle, or any other plane figure. more examples on math tutors online.

Geometrical point

Welcome to free math help online,
A "point" in geometry can be thought of as something
with no length, width, or breadth. Everything in the real world has
some length, width, and breadth; we can only approximate a point by
making a dot with the sharpest pencil we can get. free math; (Physicists now
think that electrons may actually be points, but electrons obey the
laws of quantum physics, which is rather more complicated than
ordinary geometry.)

Still, somehow, geometry is very useful in describing the real world,
even though strictly speaking, it describes things that don't exist in
the real world. more explanation on math forum.

Counting calender numbers

Greetings from free online math help,

In short, since the historical/calendric situation is so messy, I
believe that we should measure the millennium by noticing when the big
party is, and Prince doesn't party like it's 2000. I think we're in
the new millennium now.

It's also worth noting that since there was no year zero, the years
transitioning from BCE to CE are numbered ... -3, -2, -1, 1, 2, 3, ...
But some people, free math; notably astronomers, want the math to work out
better, so they actually use a year zero (... -2, -1, 0, 1, 2, ...),
so they're one year off from the rest of us in negative-land.

Understanding math

Welcome to online math tutors,
It wasn't until I got to college, where they started dealing with the
components of molecules (atoms and electrons) that chemistry started
making sense. That's where they should have started, and there is no
telling how many kids had their interest in the subject killed by
starting at the other end.

Similarly, mathematics is, by and large, taught backward. You are
drilled on little skills, which turn out to be important, but without
ever really being shown the bigger picture, which would help you
understand _why_ they are important.

Can you imagine trying to teach
someone to play chess by having them practice moving the individual
pieces, math helper ;without ever letting them know that there was such a thing as
a chess 'game', or even letting them see a board with more than one
piece on it? Who would bother to learn it? That's something like the
way we currently go about teaching math. Is it any wonder that so many
students lose interest so early?

Learn to enjoy math

Welcome to free online math help,
Actually, math starts to get _fun_ in 7th and 8th grade. You stop
dealing with particular numbers, and start dealing with patterns,
which are much more powerful, and therefore much more interesting. meet free online math tutors.

I don't believe that anyone can stay focused for long on a subject
that she doesn't like, so my advice would be to learn to enjoy math,
instead of looking at it as something that you're 'supposed' to learn.

Philosophy of Mathematics

Welcome to free math help online,

There is a philosophy whose purpose is to help people get past this
"freezing" business. It's called Zen Buddhism. (I know, that _sounds_
like a religion, but it isn't.) You can read a really nice, short,
simple introduction to the ideas of Zen Buddhism in a book called _Zen
in the Martial Arts_, by Joe Hyams. online math tutors ;(I know, that _sounds_ like it's
going to be a book about karate, or judo, but it isn't. At least, not
mostly.) It's a pretty popular book, so you should be able to find it
in most libraries or bookstores. It would be well worth your time to
read it.

This probably isn't what you wanted to hear, but it's better that you
should find out sooner rather than later. learn more with free online math tutoring.

Chess related to math

Welcome to free math tutoring,
It's a little like what you do when you invent a board game like
chess. You specify that there are such-and-such pieces, and they can
move in such-and-such ways, and then you let people explore which
board positions are possible or impossible to achieve. 

The main difference is that in chess, you're trying to win, while in
math help, you're just trying to figure out what kinds of things can - and
can't - happen. So a 'chessamatician', instead of playing complete
games, might just sit and think about questions like this:

 If I place a knight (the piece that looks like a horse, and moves
 in an L-shaped jump) on any position, can it reach all other
 positions?

 What is the minimum number of moves that would be required to get
 from any position to any other position?

Introduction of Mathematics

Hi
I am your math helper,

mathematics is the derivation of
theorems from axioms.

So what does that mean?

It means that mathematics is a collection of extended, collaborative
games of 'what if', played by mathematicians who make up sets of rules
(axioms) and then explore the consequences (theorems) of following
those rules, more examples in math forum,

For example, you can start out with a few rules like:

A point has only location.
A line has direction and length.
Two lines interesect at a point.

ln x

Let us learn about ln x

A function in general tells the y value for the corresponding x value. The inverse of a function will tell you which x value to get that value of y.

An inverse function f ^-1

• For every x in the domain of f, f ^-1[f(x)] = x, and
• For every x in the domain of f ^-1, f[f ^-1(x)] = x

The domain of function f is the range of inverse function f ^-1 and the range of function f is the domain of inverse function f ^-1.

The differentiation is the branch of calculus. There are two types of calculus namely Integral calculus and differentiation calculus . The differentiation is nothing but the finding derivatives of the given function and the integral deals in solving indefinite or definite integrals. In this article we shall discuss about differentiation of ln x related problems. The following are the examples related to differentiation of ln x.

Differentiate Ln X:

Example 1: Differentiate ln x
Solution: Let f(x)= ln x
Differentiating f(x), we get
f'(x) = 1/x
So, the solution is 1/x

Factor by grouping

Factoring by grouping is usually done when you have at least 4 terms and they do not look to have anything in common. The procedure for that is:

Factor by grouping, in layman language, is simply defined as the grouping of terms with common factors before factoring a polynomial. A polynomial is a mathematical expression that is formed by variables and constants. The construction of such variables and constants is done by using operations of addition, subtraction, multiplication and non-negative whole number exponents (constants). Before we get down to factor by grouping methods

In mathematics, factoring is one of the important topic in algebra. Given expression can be factored by using the method of factoring by grouping. The given polynomial expression can be factored by different methods that are factoring by grouping, using trinomials by ac method, and group the polynomials more than two groups. Let us solve some example problems in factoring by grouping.

Time

Let us learn about "Time"

Time is quantified in comparative terms or in numerical terms using units Time has been a major subject of religion, philosophy, and science, but defining it in a non-controversial manner applicable to all fields of study has consistently eluded the greatest scholars.

Time is represented through change, such as the circular motion of the moon around the earth. The passing of time is indeed closely connected to the concept of space.Student know tutor time locations to schedule their time for studies.

Time is very precious especially for students. "The key is to have a balanced life. Set aside a fraction of your time to carry out your dreams and ambitions."

Time is limited, Time is scarce, You need time to get what you want out of life, You can accomplish more with less effort, Too many choices

Because a student's time is so valuable, it is important to use it wisely. This can be done by taking advantage of idle time that could be spent studying. This could happen during lunch, on the bus ride to and from school or before a class starts. By taking advantage of these extra minutes, you will more efficiently use your time, reducing time spent studying at home, which will leave time for other activities.

Another useful tip is to find out when you do your best work. Some students are night owls and perform well late into the evening. Others perform better in the morning. Find out which time works for you and concentrate studying and assignment efforts during that period. This uses your time more effectively.

Introduction to factoring quadratic equation

Let us study about Factoring quadratic equation,

An equation is in the form of y= ax² + bx + c, where a, b, c are variables with a not equal to zero is called as quadratic equations. When we graph the quadratic equation, we will get a curve called as parabola.

Parabolas are the curvature that be able to open upward or downward depending the sign of a and it may vary in its "girth", but all the parabolas have the same basic "U" shape.

I hope the above explanation was useful, now let me explain Quadratic Equation Problems

quadrants of a graph

Hi Friends!!!

Let us learn about "quadrants of a graph"

-->Quadrant is the word helps us describes the parts. If you draw straight and perpendicular lines, divide the page into four parts, each called a quadrant graph.

Graph contains four quadrants.

Large amount used one is the 1st quadrants graph which is on the top right.

The left of it is declaring the second quadrants.

The third is the one below the second quadrants.

One on the graph that is below the first quadrant is specified the fourth quadrants graphs.

Graphs are a generalization of trees. Like trees, graphs have nodes and edges

Graphs are pictures that help us understand amounts. These amounts are called data. There are many kinds of graphs, each having special parts.

My skills tutors helped me to learn graph.

What is Odd function

Let us study about Odd function,
Here we are going to learn even and odd functions. Even and odd functions are very useful in graphing and symmetry. Whether a function is even or odd can be said using some algebraic calculations.
Every plot may not have symmetry so there is no need that every function should be even or odd. That is a function can be even or odd or might not be both. Now we will separately learn even and odd functions.

I hope the explanation was useful, now let me explain decimal place value chart.

horizontal asymptotes

Hi Friends, Good Evening!!!

Let us learn about "horizontal asymptotes"

Asymptote is a tangent which touches any curve at infinity , so that we cannot meet the curve and the line in real. We study 3 types of Asymptotes viz. Vertical, Horizontal and Slant/oblique Asymptote. Also in standard terms, Horizontal asymptotes are horizontal lines that the graph of the function approaches to 0 on x axis as x tends to +∞ or −∞. Similarly Vertical asymptotes are vertical lines and the graph of the function approaches to 0 on y axis as y tends to +∞ or −∞. Vertical asymptotes are straight lines near which the function grows without bound.When curve doesn't have Vertical or Horizontal then it contains Slant Asymptote.

Y=0 is and example of Horizontal asymptotes and similarly X=0 is an example of vertical asymptotes

Horizontal asymptotes are horizontal lines the graph approaches.

Horizontal Asymptotes CAN be crossed.

To find horizontal asymptotes:

* If the degree (the largest exponent) of the denominator is bigger than the degree of the numerator, the horizontal asymptote is the x-axis (y = 0).

* If the degree of the numerator is bigger than the denominator, there is no horizontal asymptote.

* If the degrees of the numerator and denominator are the same, the horizontal asymptote equals the leading coefficient (the coefficient of the largest exponent) of the numerator divided by the leading coefficient of the denominator

One way to remember this is the following pnemonic device: BOBO BOTN EATS DC

* BOBO - Bigger on bottom, y=0

* BOTN - Bigger on top, none

* EATS DC - Exponents are the same, divide coefficients

Geometry Parts of a Circle

Let us study about the Parts of a circle,
A line to create a circle contains no start otherwise finish; it is a easy closed curve.
* Either point lying on the circumference of a circle is the equal distance as of the middle of the circle.
* A line section as of a point lying on the circumference of a circle to its middle is known as the radius.
* Both line segment to start and ends on the circle’s circumference is known as a chord.
* A chord to exceeds during the middle of a circle is known as the diameter.
The diameter of either circle is double as long as circle within the radius. Each circle contain an infinite number of radii also diameters. For a known circle, every diameters are congruent also every radii are congruent. A chord is a line part that connecting two points on a curve. Within geometry, a chord is frequently utilized to illustrate a line part connecting two endpoints that lie on a circle.
I hope the above explanation helped you.

height conversion

Hi Friends, Good Afternoon!!!

Let us learn about "height conversion".

I guess you practiced about Venn Diagram which we discussed in our previous blog.

Conversion of heights is specified in either centimeter, meters , feet and inches. The height can be converted from cm to feet, meter into feet and etc. in conversion the unit should be mentioned such as cm or feet.
1 centimeter = 0.033 feet
1 feet = 30.48 centimeter, same like
Height converter Cm to feet
2 centimeter = 0.065 616 797 9 feet
3 centimeter = 0.098 425 196 85 feet

2 feet = 60.96 centimeter
3 feet = 91.44 centimeter
In our next blog we shall learn about "inch centimeter conversion"

Explain Interval notation

Let us study what is Interval notation,

An interval can be shown using set notation. For instance, the interval that includes all the numbers between 0 and 1, including both endpoints, is written 0 ≤ x ≤ 1, and read "the set of all x such that 0 is less than or equal to x and x is less than or equal to 1."

The same interval with the endpoints excluded is written 0 <>

Replacing only one or the other of the less than or equal to signs designates a half-open interval, such as 0 ≤ x <>intervals. In this notation, a square bracket is used to denote an included endpoint and a parenthesis is used to denote an excluded endpoint. For example, the closed interval 0 ≤ x ≤ 1 is written [0,1], while the open interval 0 <: x <>
I hope the above explanation was useful, now let me explain Factorisation.
