Calculates the sine of an angle.
sin() is useful for many geometric tasks in creative coding. The values returned oscillate between -1 and 1 as the input angle increases. sin() calculates the sine of an angle, using radians by default, or according to if angleMode() setting (RADIANS or DEGREES).
sin() can also be used in shaders with p5.strands. The following example uses sin() to oscillate the color of a shape over time.
Examples
Syntax
sin(angle)
Parameters
angle
Number: the angle, in radians by default, or according to if angleMode() setting (RADIANS or DEGREES).
Returns
Number: sine of the angle.
