Question

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 sec^4x = cot x + 2 tan x tan^3x 
2. ( sin x)(tan x cos x - cot x cos x)= 1- 2 cos^2x
3. 1+ sec^x sin^x = sec^2x
4. sin x/1-cos x + sin x/1+cos x = 2 CSC x
5. - tan^2x + sec^2x = 1
