# What are the exact roots for csctheta is undefined in 0^circ<=theta<360^circ?

See explanation.

#### Explanation:

According to definition we have:

## $\csc \theta = \frac{1}{\sin} \theta$

So $\csc \theta$ is undefined for those values of $\theta$, for which $\sin \theta = 0$

If we solve this equation we get:

## x = kpi; k in ZZ

In the given interval we have:
