Homework Help: URGENT - Trigonometry - Identities and Proofs

Posted by Veronica on Saturday, April 2, 2011 at 12:01am.

Okay, today, I find myself utterly dumbfounded by these three questions -
Write a proof for -
2/(sqrt(3)cos(x) + sin(x))= sec((pi/6)-x)
Solve the following equation -
2sin(2x) - 2sin(x) + 2(sqrt(3)cos(x)) - sqrt(3) = 0
Find all solutions (exact) to the equation -
sin^2(x)cos^2(x) = (2 - sqrt(2))/16
Any Help at all will most definitely be appreciated!!!
