Question 342338: Proving trigonometric identities! Please prove this! :(( Thank you!
(1+cos3θ)^3/2 = 2sqrt(2) [1-sin^2 (3θ/2)] cos(3θ/2)
Answer by Alan3354(69443) (Show Source): You can put this solution on YOUR website!
(1+cos3θ)^3/2 = 2sqrt(2) [1-sin^2 (3θ/2)] cos(3θ/2)
-----------
(1+cos3θ)^3/2 is the exponent 3? or 3/2?
