Question: i) Prove the identity ii) Solve the equation 5 sin cos 0 = (cos sin) (cos + sin) for 0 180.

i) Prove the identity


sin cos tan 0 (cos-sin)(cos+sin 0) (1-tan0)



ii) Solve the equation 5 sin cos 0 = (cosθ − sinθ) (cosθ + sinθ) for 0° ≤ θ ≤ 180°.

sin cos tan 0 (cos-sin)(cos+sin 0) (1-tan0)
