Question

PLEASE HELP ASAP!!!!

Answer 1

Explanation:

`- \csc { }^(2) (9) + \cot {}^(2) (9)`

`- \frac{1}{ \sin {}^(2) (9) } + \frac{ \cos {}^(2) (9) }{ \sin {}^(2) (9) }`

`- ( \frac{1}{ \sin {}^(2) (9) } - \frac{ \cos {}^(2) (9) }{ \sin {}^(2) (9) } )`

`- ( \frac{ \sin {}^(2) (9) }{ \sin {}^(2) (9) } )`

`- (1)`

`- 1`

The answer is -1
