i think it is a 4 unit math problem,lol

Try a substitution of x= 2sin@

Also don't forget about double angle formulae.

Well if they don't give you the substitution then it is a 4U question. In 3U they'll always tell you which substitution to use.

Yup, that's a 4 unit question. It looks remarkably like question 1a) of monday's 4u HSC paper.

Yeah, it does look a bit like it, hehe. Except the numerator had an x.
