Hello everyone!(adsbygoogle = window.adsbygoogle || []).push({});

I was wondering.. if you could help me calculate some integrals:

It's not for Homework or something, just my curiosity:

[tex]\displaystyle{\int}\sqrt[3]{x^2-1} dx[/tex]

What would you suggest? I tried substitution, thou it seems to me useless.

Are these integrals common in tests and exams? I mean, they seem to me just pure mathematics, i.e. - no application, and I'm not sure, if that's not too much to ask from a student..

Thanks in Advance, Marin
