Can anyone help me through the following integral? I already know the solution, the process of finding it is what I am concerned with.(adsbygoogle = window.adsbygoogle || []).push({});

(Not sure what the proper notation is for writing this on a forum)

Int(sqrt(a^2sin^2(t)+b^2cos^2(t))dt from t = 0, t = 2pi

I tried simplifying by dividing through with a bcos(t) so the sqrt would be tan^2+1 and so forth. This really didn't get me anywhere, however. All help is appreciated.
