WolframAlpha

                                    

WolframAlpha is a powerful web based application that supports a lot of function.

 WolframAlpha supports mathematics, physics, chemistry, engineering, etc...  But 

mathematics concerns us.

 Wolfram|Alpha can guide you step by step through the process of solving many mathematical 

problems, from solving a simple quadratic equation to taking the integral of a complex 

function.When trying to find the roots of 3x2+x–7=4x, Wolfram|Alpha can break down the steps

 for you if you click the “Showsteps” button in the Result pod.

As you can see, Wolfram|Alpha can find the roots of quadratic equations.,

 Wolfram|Alpha shows how to solve this equation by completing the square and then

 solving for x. Of course, there are other ways to solve this problem!

Wolfram|Alpha can demonstrate step-by-step solutions over a wide range of 

problems. This functionality will be expanded to include steps for solutions in other 

mathematical areas. Look through the following examples to see the abilities of the 

“Show steps” functionality.

If you need to learn how to do long division of polynomials, Wolfram|Alpha can show

 you the steps. 

Let’s try (x5–14x4+3x2–2x+17)/(2x2–x+1):

Wolfram|Alpha also has the step-by-step functionality for partial fractions. Try partial 

fractions of 1/(x3–1):

The step-by-step programs in Wolfram|Alpha rely on a combination of basic algorithms

 and heuristics including Gaussian elimination, l’Hôpital’s rule, and Bernoulli’s 

algorithm for rational integration. These heuristics are a logical formulation of the 

natural methods used by humans for solving problems. By utilizing Mathematica’s 

powerful pattern-matching capabilities, Wolfram|Alpha’s developers have morphed 

these rules into a platform for breaking down and structuring the solutions to 

complicated problems, which closely mimics the ways by which a human would solve

 problems of these natures.

Using of Wolfram alpha is very easy. You can write anyting about math in the text box and press enter key then, WolframAlpha solves it.

WolframAlpha can be used in schools, labs. It can be helpful for students and teachers. And you can use it at home for specific purposes
