Verify each trigonometric equation by substituting identities to match the right hand side of the equation to the left hand side of the equation. 1. cot x sec*x = cot x + 2 tan x + tan3x 2. (sin x)(tan x cos x - cot x cos x) = 1 - 2 cos2x 3. 1 + sec2x sin2x = sec2x 4. sin x sin x + = 2 CSC X 1- COs x 1+ Cos x 5. - tan2x + sec2x = 1
