$\frac{1}{\tan (180)}$

Step 1

Apply the reference angle by finding the angle with equivalent trig values in the first quadrant. Make the expression negative because tangent is negative in the second quadrant.

$\frac{1}{- \tan (0)}$

Step 2

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

$\frac{1}{- 0}$

Step 3

Multiply $- 1$ by $0$ .

$\frac{1}{0}$

Step 4

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