Does anybody know substitutions that can be used for the following integrals:(adsbygoogle = window.adsbygoogle || []).push({});

[tex]

\int (a^2 - b^2 \cos\theta)^{-3/2} d\theta

[/tex]

[tex]

\int (a^2 - b^2 \cos\theta)^{-3/2} \sin\theta d\theta

[/tex]

[tex]

\int (a^2 - b^2 \cos\theta)^{-3/2} \cos\theta d\theta

[/tex]

I also had a look for these in my table of integrals, but didn't see anything appropriate, but am also a bit rusty, and could just be overlooking the obvious.

EDIT: oops. fixed sign in square root.
