    Integration by Parts of a secant function

    Okay, I'm supposed to do integration by parts with this problem:

    ∫ sec^n(x) dx

    I'm sure how to go about doing this though.

    Could someone explain the steps?

    See if you can get somewhere with:

    \text{sex}^n(x)=\pm \left[1+\tan ^2(x)\right]^{\frac{n}{2}}
