Trigonometry Identities

[itsclaire9]

I have a take-home test due Monday (we're allowed to use notes, tutors, friends, textbook etc to finish the test) and this one problem hurts my brain. We're learning about solving Identities in Trig right now, all that sin and cos stuff. Here I've provided a picture of the problem as it would be really difficult to clearly type it out.
