\cos (360)

$\cos (360)$

Step 1

To convert degrees to radians, multiply by

\frac{π}{180 °}

$\frac{π}{180 °}$ , since a full circle is

360 °

$360 °$ or

2 π

$2 π$ radians.

Step 2

Remove full rotations of

360

$360$ ° until the angle is between

0

$0$ ° and

360

$360$ °.

\cos (0) \cdot \frac{π}{180}

$\cos (0) \cdot \frac{π}{180}$ radians

Step 3

The exact value of

\cos (0)

$\cos (0)$ is

1

$1$ .

1 \cdot \frac{π}{180}

$1 \cdot \frac{π}{180}$ radians

Step 4

Multiply

\frac{π}{180}

$\frac{π}{180}$ by

1

$1$ .

\frac{π}{180}

$\frac{π}{180}$ radians

\cos (360)

$\cos (360)$
