Prove the following identities. These are grouped by "strategy" for easy practice. Use factoring: 1. sin x-sin x cos x=sin* x tan x-tan x sin x=sin x 2. sin x cos x - sin x=-sin x 3. sec x tan x+ sec x = sec' x 5. tan 9-tan sin = sin cos 0 Prove the following identities. These are grouped by "strategy" for easy practice. Use factoring: 1. sin x-sin x cos x=sin* x tan x-tan x sin x=sin x 2. sin x cos x - sin x=-sin x 3. sec x tan x+ sec x = sec' x 5. tan 9-tan sin = sin cos 0
