*As an aside, I'm sorry if my formatting on the equations isn't up to par. If anyone would be willing to tell me how to do it properly- if there is a way-, I'd be glad to learn.

Hi all.~ I've spent my entire day with my nose figuratively jammed into my Pre-Cal book and still can't seem to be able to figure these out; I can't even manage tostartthem. If anybody could help me at some point tonight that'd be lovely.

**Essentially, I have to find all of the solutions for the equations on the given intervals**

These Three are on the Interval [0, 2pi)1. 3sin 2x - (3/2) sqrt3 = 0

2. 2sec^2(x/2) - 3sec(x/2) - 2 = 0

3. -sqrt3 cosx + sinx = -sqrt3

This One is on the Interval [-pi, pi]4. cos2x + 5sinx = -2

A huge thank you to anyone willing to help! This has been killing me.
