True Math

Welcome to free online math help,

Let us study what is mathematics with math helper,

Mathematics can be defined as the construction and exploration of
formal systems. The advantage of this definition is that it emphasizes
the somewhat subtle point that mathematics IS formal -- which is just
another way of saying that it has no NECESSARY relation to anything in
'the real world'.

What all this means is that what is 'true' in mathematics depends
entirely on what axioms you start with, and what rules you use to
combine them. To take your example of 'proving' that the product of
two negatives is positive -- your result is true given the system you
set up, but it may be false in other systems.

I hope the above explanation was useful, now let us study more examples on math forum.

Math and Art related

Math and Art related :

We all need math help and we use it every day, sometimes without even realizing it! Here are some situations that you may find yourself in on any given day. Each one involves the use of help in math skills. Don't be scared! The checkout lady will not give you a test on your math skills on the spot. These are just examples of how a basic knowledge of math can come in handy.
Almost any artist will tell you that there is some kind of mathematical or symmetrical pattern involved in creating pictures. Art doesn't necessarily require addition, subtraction, division, or multiplication. There is, however, a great need for geometric shapes and figures. Notice the picture at the top of the screen. There are some triangles, squares, rectangles, and parallelograms found in each of the images found in the picture.

Hopefully after viewing this stack free math tutoring online, you will understand a little better how math and art can be related through geometry!

Introduction for Poisson equation

Let us study about Poisson Equation,

Poisson distribution is a limiting case of Binomial distribution under the following conditions.

(i) n the number of trials is indefinitely large ie., n → ∞.

(ii) p the constant probability of success in each trial is very small ie., p → 0.

(iii) np = λ is finite where λ is a positive real number. When an event occurs rarely, the distribution of such an event may be assumed to follow a Poisson distribution.

Definition: A random variable X is said to have a Poisson distribution if the probability mass function of X is

P(X = x) =e−λ λx/x!, x = 0,1,2, …for some λ > 0.

I hope the above explanation was useful, now let us study linear programing

How to solve radical fractions

Let us study how to solve radical fractions,

Mainly addition and subtraction problems are solved using the radical fractions.

For the addition problems, the numerator term are simplified first.

* Then, in the next step, we have to take the conjugate for the given problem.
* After that the multiplication are made to the obtained result.
* Then finally simplify the obtained terms.

For the subtraction problems, the numerator term are simplified first.

* Then, in the next step, we have to take the conjugate for the given problem.
* After that the multiplication are made to the obtained result.
* Then finally simplify the obtained terms.

Geometry Basics:Geometry Basics consists of some basic concepts like points, lines, planes etc.Let us now understand the circle properties.We have two properties of circle. They are area and circumference of a circle.Area of a circle is how much space available inside a circle. It is measured by square units. Area of circle can be calculated by following formula,Area A = π x Radius2.Circumference of a circle is the total distance around a circle. It is measured by units. Circumference of circle can be calculated by following formula,

Circumference C = 2 x π x Radius Here π = 3.14

Let us see some sample problems of circle using symbol r.Let us lastly understand about Tangent Circles. Two intersect circles in a single point is known as tangent circles.Hope you like the above example of Goemetry Basics.Please leave your comments, if you have any doubts.

Factoring expressions by grouping

Let us study about factoring expressions by grouping,

Introduction to factoring expressions by grouping:

In mathematics, factoring is one of the interesting topics in algebra. Using the grouping method, given polynomial expression can be factored.

Polynomial expressions are the sums of a finite number of monomials. It has more than one term and it has a constant value for the each term, for that variable power of integral is raised to more than two.

Perimeter of a rectangle

Let us study about Perimeter of a Rectangle,
The perimeter of a polygon is out side distance of the polygon. A polygon is 2-dimensional; but, perimeter is 1-dimensional and is measured in linear units.

To find the perimeter of a polygon, take the sum of the length of each side.

The perimeter of a rectangle is ,out side distance of the rectangle.A rectangle has four sides,they are equal in length. The formula for finding the perimeter is Side A + Side B + Side A + Side B. This could also be stated as 2*Side A + 2*Side B or 2*(Side A + Side B) .
