This integral is not overly complicated, but I am having a little trouble with it - I haven't been in calc for a year almost, and it seems I have lost my integration abilities with it.(adsbygoogle = window.adsbygoogle || []).push({});

Here's the integral:

[tex]\int \sqrt{1 + (a \pi x^{a-1})^{2} \cos^{2}({\pi x^{a}})} dx[/tex]

I figure the best place to start is to factor out the inside expression and get rid of the square root, but even doing this I am lost.

Any help?
