Interface:

The presented program is able to calculate integrals of the form:

•                      Calculate the multiple integral
•                      Calculate the definite integral
•                      Evaluate the double integral
•                      Calculate the derivative of any order

•                       sqrt(x) square root of X or any other variable
•                       e Euler number 2.71828182834905 ...
•                       ln(x) of natural logarithm X
•                       pi number π ≈ 3,1415926535 ...
•                       ^ Exponentiation

Enter integrands multiple integral is performed from the innermost to the outermost. Before evaluating the integral of the order entered. The theoretical maximum of the order of the integral is ~ 100, the complexity of the algorithm: (1000^n), where n - the order of the integral. Complex triple integrals can be calculated from 5 minutes. The average computation takes 10 seconds.
 

Example of calculating a triple integral:

Let us solve the following integral:


 

 

What is the correct answer:



In the sample is taken variable t = 1 - x, then x is integrated over and gets the response I = 2, which coincides with the value of the integral obtained in the program.
