# Cos

Compute cosine of an angle in degrees.

## Input/Output

Similar to the function Sin but instead, the output value starts from 1. Outputs value between 1 and -1 depending on the given input which, scales from angular (0°–360°)

## Notes

Additionally, there are only 4 certain points where you can get a whole number:

- 0°/360° = 1
- 90° = 0
- 180° = -1
- 270° = 0

To understand better, search for "Trigonometric functions."

## Example

- You can refer to the example in sin.
