I know that . I can't see how this helps!!for
Integration by parts isn't useful either as it makes an infinitely long sequence.
Macluarin expansions also don't help. They make something very messy.
gah!!
umm, I want to find an expression for the integral.
I have the answer, but I can't work out how to get there.
I get stuck on having and . Is there a way to change these into just ? (my question gives the answer in terms of just ).
Double angle formulae don't work for this part either...
Well there's no need.
I walked into todays lecture and he changed the question completely!
I like your method Moo, i'll remember that for another time (hopefully for a similar question in the future!).
If anyone can actually integrate this between the limits I would really like to see how it's done. It's really quite puzzling.
