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)...
2sin^2x - 1÷ sinxcosx = tanx-cotx
(1-cos^2x)(cot^2+1) = 1
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,...
∫1 1 dx =¶ + 1 0 (1+x2)2 8 4
Prove that 1 +sin b -cos b=2sin 1 b cos 1 b +sin 1 b ...
Jay is 120 meters from the base of a building and Mary is 40 meters from the base of the building. Jay's angle of elevation when looking at the top of the building is X and Mary's is 2X. What is the...

Complete the identity: csc(t)(sin(t) + cos(t)) = ?
Prove a^2(1+cos)=1-cos if 1-a^2)sin - 2acos =0
sec^2(x)-sec^2(x) csc^2(x)
Secx-tanxsinx=1/secx
csc2(x/2)=2sec(x) Please help me solve for x.
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..
