I'm not sure where to post bugs, but this one is pretty severe.
simplify(â(1-x^3)*int(â(1-x^3),x)) gives a completely wrong result: (-2*x^4+5*x)/5
You can replace "*" with "+", "-" or "/", replace "x^3" with for example "x^4" or "â(1-x^3)" with lots of different functions of x (e.g. âln(x)) yielding different, but also completely wrong results, so the problem is not limited to elliptic integrals.
Please fix this as soon as possible, thanks.
