I just want to get help with a few and then I'll see if I can figure out how to do them on my own..

Ok so here is the first type of problem I have.

Solve each trig equation.

First off I'm not entirely sure what I'm trying to find in the following. Even then I don't really know where to start.

1. sin x = -sqrt2/2

2. Cos 2x=-sqrt2/2

3. tan .5x= sqrt3

4. sqrt3 sec x +2 =0

I think if i know how to do those I will be able to figure out the rest of those type of problems.

Here id the other type of problem i have to do.

Solve the each trig equation

1.4 sin^2 x-3=0

For this one would I just add 3 then divide by 4. Then take the inverse sin of sqrt of 3/4 and the answer would be 1.047. If that is right then that would be one of the solutions but Im not sure how to find the other one

2. cos x +2= 3cos x

3. 2 sin ^2 x-3=0
