# How do you find the value of csc pi?

$\csc \left(\pi\right)$ is undefined
$\csc \left(x\right) = \frac{1}{\sin} \left(x\right)$
We have $\sin \left(\pi\right) = 0$, therefore $\csc \left(\pi\right) = \frac{1}{0}$ which is undefined and has different limits when approached from above and below ($\pm \infty$).
