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 sec4x = 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
sine of x divided by one minus cosine of x + sine of x divided by one minus cosine of x = 2 csc x
- tan2x + sec2x = 1
step by step please
