Question
use identities to find the indicated value for each angle measure? determine all solutions of the equation in radians? find the exact value of the real number y? give the degree measure of 0
#34,36 (really important) #38-42( not really sure how to do those numbers) please help!!

34) sin theta = -4/5
cos theta = 3/5
cos 2 theta = cos^2 theta - sin^2 theta
(3/5)^2 - (-4/5)^2
= 9/25 - 16/25
= - 7/25
