tan3x - tan2x- tanx = tan3xtan2xtanx
tan3x - tan2x- tanx = tan3xtan2xtanx
sin(X)sec(x)=1-(cos^2)x/sin(X)cos(X)
This is for my trig class. Thanks for the help!

This is for my trig class, and the directions say to verify the identity. Thanks so much.
1) given the double angle identity for cosine: cos2θ=cos2θ-sin2θ Prove: cos3θ = cos3θ - 3cosθsin2θ and: cos4θ = cos4θ - 6cos2θsin2θ + sin2θ 2)...
(1-cos^2x)(cot^2+1) = 1
2sin^2x - 1÷ sinxcosx = tanx-cotx
cosx = (1- tan^2 x/2) / 1 + tan^2 x/2) Completely stuck.
Explain how you could determine the exact value of (sec 7pi/6) if you know the value of (sin 11pi/6). Prove with diagrams. I've no idea how to do this question that's worth 10 marks...
Prove 1 - sin2x / cosx = sin2x / 2sinx I tried do both LHS and RHS. Got stuck after a step or two.
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,...
