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.
