Question

What is the step by step equation for

Answer 1

Explanation:

this might be the answer

Answer 2

First, know that
`csc(x)=(1)/(sin(x))`:

`(1)/(sin^(2)(x)) *cos^(2)(x)=(cos^(2)(x))/(sin^(2)(x))`

Remember that cos²(x) + sin²(x) = 1, so cos²(x) = 1 - sin²(x):

`(cos^(2)(x))/(sin^(2)(x)) =(1-sin^(2)(x))/(sin^(2)(x)) =(1)/(sin^(2)(x)) -(sin^(2)(x))/(sin^(2)(x)) =csc^(2)(x)-1`
