Help with AP Calculus summer assignment?

I’ve been working on this summer assignment for a while now, and I’ve managed to solve 47 out of the 50 assigned problems,but I’m having difficulty solving 3 of the problems. Any help would be greatly appreciated. =)

1.) (Let * = pi)

sin^2 (167*/4) + cos^2 (167*/4) = ?

2.) Let @ = theta

1/2(cos 2@ + 1) is equal to…?

3. The solution set of 4 sin^2@ – 3 = 0, 0 degrees is less than or equal to theta, which is less than 360 degrees, is…?

1) tsk…cos ² Θ + sin ² Θ = …you should know
2) trig identities…cos 2 Θ = again you should know…there are 3 results for this identity…
3) sin ² Θ = 3/4 and you should know {trig} the angles for sin Θ = ± √ 3 / 2
