$\frac{\frac{\csc (- 1)}{\cot (0)}}{\frac{\cot (0)}{\csc (1)}}$

Step 1

Rewrite $\cot (0)$ in terms of sines and cosines.

$\frac{\frac{\csc (- 1)}{\frac{\cos (0)}{\sin (0)}}}{\frac{\cot (0)}{\csc (1)}}$

Step 2

The exact value of $\sin (0)$ is $0$ .

$\frac{\frac{\csc (- 1)}{\frac{\cos (0)}{0}}}{\frac{\cot (0)}{\csc (1)}}$

Step 3

The expression contains a division by $0$ . The expression is undefined.
