Hi. Can you verify the following:

Question

(cosθ) / (sinθ – 1) + (cosθ)/ (1 + sinθ)

(1 / cos^2θ) – (2) (1/cos^2θ) (sinθ / cosθ) + (sin^2θ / cos^2θ)

Answer 1

I see no equal signs
What are we verifying ?

Answer 2

Oooops. Its this one. Sorry.

(cosθ) / (sinθ – 1) + (cosθ)/ (1 + sinθ) = -2tanθ

(1 / cos^2θ) – (2) (1/cos^2θ) (sinθ / cosθ) + (sin^2θ / cos^2θ) = (1 - sinθ) / (1 + sinθ)
