I am trying to integrate a very messy expression using Wolfram online integrator but I get the message:
"You need to use Mathematica to evaluate this expression".
The online integrator works only for relatively simple expressions.
Unfortunately I do not have a license for Mathematica.
Any proposal to overcome this?
Is there a free computer algebra software that can be used as a replacement to Mathematica.
This is not my expression.
When I type an expression similar to my expression (A*x*Hypergeometric2F1[1,2,1,x^2]) in Wolfram Alpha I get a very simple answer which cannot be correct.
I checked this by differentiating the answer.
