Question

PLEASE help me verify the identity!!

Answer 1

Explanation:

`\frac{ \tan {}^(2) (x) + 1 }{ \tan {}^(2) (x) } = \csc {}^(2) (x)`

`\frac{ \tan {}^(2) (x) }{ \tan {}^(2) (x) } + \frac{1}{ \tan {}^(2) (x) } = \csc {}^(2) (x)`

`1 + \frac{1}{ \tan {}^(2) (x) } = \csc {}^(2) (x)`

`1 + \cot {}^(2) (x) = \csc {}^(2) (x)`

`\csc {}^(2) (x) = \csc {}^(2) (x)`
