Answer 1

Answer:

your question is done thanks

Answer 2

Step-by-step explanation:

Given:

(cotθ-cosecθ)^2

=> cot²θ - 2cotθcosecθ + cosec²θ

=> cos²θ/sin²θ - 2(cosθ/sinθ)(1/sinθ) + 1/sin²θ

=> cos²θ/sin²θ - 2cosθ/sin²θ + 1/sin²θ

=> (cos²θ - 2cosθ+1)/sin²θ

=> (1- cosθ)²/(1- cos²θ)

=> (1- cosθ)²/(1 + cosθ)(1- cosθ)

=> (1-cosθ)/(1+cosθ)

Hope it helps!
