Can someone please help me?

Verify each trigonometric equation by substituting identities to match the right hand side of the equation to the left hand side of the equation.

cot x sec4x = cot x + 2 tan x + tan3x

(sin x)(tan x cos x - cot x cos x) = 1 - 2 cos2x

1 + sec2x sin2x = sec2x

[(sin(x))/(1-cos(x))]+[(sin(x))/(1+cos(x))]=2csc(x)

- tan2x + sec2x = 1

This is as far as ive
 gotten
$$\frac{ 1 }{ sinxcos^3x }$$
