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?

If anyone has software that could integrate this, or can recommend some (preferably freeware), I'd appreciate it. I don't need the work - I just need the answer.
