\tan (450 °)

$\tan (450 °)$

Step 1

Rewrite

\tan (450 °)

$\tan (450 °)$ in terms of sines and cosines.

\frac{\sin (450 °)}{\cos (450 °)}

$\frac{\sin (450 °)}{\cos (450 °)}$

Step 2

Remove full rotations of

360

$360$ ° until the angle is between

0

$0$ ° and

360

$360$ °.

\frac{\sin (450 °)}{\cos (90)}

$\frac{\sin (450 °)}{\cos (90)}$

Step 3

The exact value of

\cos (90)

$\cos (90)$ is

0

$0$ .

\frac{\sin (450 °)}{0}

$\frac{\sin (450 °)}{0}$

Step 4

The expression contains a division by

0

$0$ . The expression is undefined.

Undefined
