Ya, I wouldn't touch Vista with a 10 foot pole ... but Office 2007 on the other hand is the best thing ever. :D

--- Quote from: "Toothpick" ---(cosx)^2 + (sinx)^2 = 1
=> (cosx)^2 = 1 - (sinx)^2

...blah blah blah tons of working out...

sinx = -1 over the given domain
x = 3pi/2

sinx = 0.5
x = pi/6
and x = 5pi/6

Well done. Perfect explanation.

Didn't think you could factorise trigs, but when anything equals "u" anything goes...

Otherwise, I think it unlikely identities are going to be on the exam. Still, cramming them because we don't get much practice on em.

Someone is 50 bound. Toothpick, you're on.
