Trigonometry
posted by Gary .
I have some trigonometric equations to do, but I'm pretty lost, and I have to get them done in a timely fashion, so any help would be much appreciated.
"Solve the following trig equations. Give all the positive values of the angle between 0 degrees and 360 degrees that will satisfy each. Give any approximate value to the nearest minute only."
1. sin 2x = (sqrt 3)/2
2. sin 2x  cos x = 0
3. sin (2x  10degrees) = 1/2
4. cos 2x  sin^2 x/2 + 3/4 = 0
5. sin^2 x = cos^2 x + 1/2
6. cos 4x = sin 2x
7. 3sin x  4cos x = 2
8. tan (x + 15degrees) = 3tan x
I know it's a lot, but even if you don't do all of them I'd be thankful.
Also, please show your work; the more detail, the better. If I can see what you're doing in detail it will help me understand.
