Question

1+cot^2(alpha)=cosec^2(alpha)​

Answer 1

Answer:

see explanation

Step-by-step explanation:

Using the Pythagorean identity

sin²α + cos²α = 1 ( divide each term by sin²α )

$\frac{sin^2\alpha }{sin^2\alpha }$ + $\frac{cos^2\alpha }{sin^2\alpha }$ = $\frac{1}{sin^2\alpha }$ , that is

1 + cot²α = cosec²α ← as required
