$\frac{1}{\tan (60)}$

Step 1

Rewrite $\tan (60)$ in terms of sines and cosines.

$\frac{1}{\frac{\sin (60)}{\cos (60)}}$

Step 2

Multiply by the reciprocal of the fraction to divide by $\frac{\sin (60)}{\cos (60)}$ .

$\frac{\cos (60)}{\sin (60)}$

Step 3

Convert from $\frac{\cos (60)}{\sin (60)}$ to $\cot (60)$ .

$\cot (60)$

Step 4

The exact value of $\cot (60)$ is $\frac{1}{\sqrt{3}}$ .

$\frac{1}{\sqrt{3}}$

Step 5

Multiply $\frac{1}{\sqrt{3}}$ by $\frac{\sqrt{3}}{\sqrt{3}}$ .
