    Hi,

    I originally posted this in the hard integrals thread but have been told to move it to its own thread here.

    I was given some basic calculus revision questions to do for an undergrad module, but since there's nothing new in them I decided to give it an A-level tag. I've been working on them for a while now, but I'm stuck at these two. Any help would be appreciated; I'm not particularly bothered if you want to post the answers as it's not an assessed homework, and I'm starting to get tired of these. :/

    Cheers,

    Tim

    35 switch hyperbolic into exponentials, then integration by parts

    or complex numbers (too advanced for A level perhaps)

    rewrite as cosec4x and use identities on one of the cosec2x

    Thanks. I'll give these a try tomorrow once my brain's had a chance to rest.

    Here are the broad strokes for Q37:

    Name:  omg.png

    You should know how to integrate cosec ^2 x wrt x.

    For the integral of cosec ^2 x * cot ^2 x wrt x, consider the structure of the integral [f(x)]^n * f(x), where f(x) =cot x and n=2.

    Hope this helps. Peace.
