you dont have to do them all just help with a few im trying to learn this for a test so if you can show work it would be a big help but if you cant its still helpful because i know what im luking for I have lost my book so please help me
1) 3 - sin x = cos(2x)
2) sec x = tan x +cot x
3)sin x - sqrt3 cos x =1
4)sin x +cos x = - sqrt2
5) cos (2x) +2 cos^2 (x/2)=2
