Someone Plz Help Me!! IDK How To Do This. Will Mark Brainliest and give thanks Just plz help me. Prove each Trigonometric Identity

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

4. sin x/1 - cos x + sin x/ 1 + cos x = 2 csc x

5. - tan²x + sec²x = 1
