    Integration

    Hi,

    Please could you give me the answer to this question, as I have no idea how to do it.

    Integrate: x ˛ 2SEC˛ x TAN x.dx

    Thanks in advance, you'd be doing me a great favour!

    integration by parts (a couple of times??), since:

    \frac{d}{dx} (\sec(x))^2=2(\sec(x))^2 \tan(x)
