Answer 1

Step-by-step explanation:

Given sinθ = a² - b² / a² + b²

(i)cosecθ = 1/sinθ

hence cosecθ= a² + b² / a² - b²

(ii)using the identity cos²θ + sin²θ = 1

hence cosθ = √1-sin²θ = 2ab/a²+b²

(iii)secθ= 1/cosθ

hence secθ = a²+b²/2ab

(iv)tanθ=sinθ/cosθ

hence tanθ = a²-b²/2ab

(v) cotθ = 1/tanθ

hence cotθ = 2ab/a²-b²
