The solution of integrals online calculator


Online calculator which helps you in solving the integrals.
For the solution of integrals apply various approximate methods, the essence lies in the fact that under the integral feature is replaced by "close" to her function, the integral of which is expressed through elementary functions.

When you use the calculator indicate these designations:
+ — addition;
- — subtraction;
* — multiplication;
/ division;
Math.cos(x) — cosine.
Math.sin(x) — sine;
Math.exp(x) — exponent;
Math.sqrt(x) square root;
Math.pow(x,n) — erection of x to the power n;
Math.log(x) natural logarithm;

Example of compliance: x^8*cos(x^4+x+2) corresponds to the Math.pow(x,8)*Math.cos(Math.pow(x,4)+x+2)
