1) given the double angle identity for cosine: cos2θ=cos2θ-sin2θ Prove: cos3θ = cos3θ - 3cosθsin2θ and: cos4θ = cos4θ - 6cos2θsin2θ + sin2θ 2)...

2sin^2x - 1÷ sinxcosx = tanx-cotx

cosx = (1- tan^2 x/2) / 1 + tan^2 x/2) Completely stuck.

Prove sec2x = 1 + tan2x I did R.H.S = 1 + sin2x / cos2x = 1 + (1 - cos2x) / (1 - sin2x) = 1 + cot2x = ??? I think I'm doing it right,...

Prove the Trigonometic identity

csc2(x/2)=2sec(x) Please help me solve for x.

Directions ask to prove the identity

Anybody have an idea how to solve that question... think needs to simplify first and use identities to solve.. but cant even start it.. please any help is welcome..
