Calculates the cosine of an angle.
cos() is useful for many geometric tasks in creative coding. The values returned oscillate between -1 and 1 as the input angle increases. cos() calculates the cosine of an angle, using radians by default, or according to if angleMode() setting (RADIANS or DEGREES).
Examples
Syntax
cos(angle)
Parameters
angle
Number:
the angle, in radians by default, or according to if angleMode() setting (RADIANS or DEGREES).
Returns
Number: cosine of the angle.
