Compute a long indefinite integral?

Posted 5 years ago

I've just joined Mathematica and I'm running the web app. I need to solve the following definite integral:

integrate[Norm[{e^2,e^3}/(e^2+e^3)-{e^(2+Cos[2Pi t]/10),e^(3+Sin[2Pi t]/10)}/(e^(2+Cos[2Pi t]/10)+e^(3+Sin[2Pi t]/10))]]

But instead of solving it, the output gives me the function still written in the integral form. How can I compute the exact indefinite integral?

Thank you!

Don't expect every integral to have a nice closed form(antiderivative). I your case, analytical solving seems impossible.

Mathematica cannot do every integral that's found in integral tables (no CAS can).
