$\csc (- x) = - \csc (x)$

Step 1

Start on the left side.

$\csc (- x)$

Step 2

Since $\csc (- x)$ is an odd function, rewrite $\csc (- x)$ as $- \csc (x)$ .

$- \csc (x)$

Step 3

Because the two sides have been shown to be equivalent, the equation is an identity.

$\csc (- x) = - \csc (x)$ is an identity
