Hello! I am having some trouble verifying a trig identity sin(4x)=4cos^3(x)sin(x)-4sin^3(x)cos(x)

2cosx - secx = cosx - tanx/cscx

Simplify the following trig expression : 1/1-sec x - 1/1+sec x

Can someone walk me through each step with an explanation? please?

How do you verify the identity?

prove (1 - cos2x)(1 - tan2x) = sin2x cos2x/1-sin2x I can't seem to solve this! Halp!!!

Prove sin4x = 4 (sin x-2 sin^3 x)/secx I can't seem to solve this! Halp!!!

prove the following identity. 1-cosθ/sin2θ = 1/1+cosθ thanks!

Verify the Identity cot2(x) − tan2(x) = csc2(x) − sec2(x)
