ok so i got this problem from and A level Past Paper, and i've been trying to solve it for quite a long time.. to no avail... i've got a feeling it's soooo easy, but nonetheless the answer just keeps eluding me... and the question goes something like this
Use the substitution t = tan(x) to find
I've been trying all sorts of trig identities.. still haven't managed to solve it xD
any help would be greatly appreciated
p.s. Sry about the layout xD
:O this was a post paper question so i was only using the identities that i was given on the booklet they usually supply with the exam.. those were not there XD guess i'll have to learn them by heart lol
but ye they were the key i managed to work it out perfectly!
Many thanks ^.^
