Math.sin()
The Math.sin() function returns the sine of a number.
Syntax
Math.sin(x)
Parameters
x-
A number (given in radians).
Return value
The sine of the given number.
Description
The Math.sin() method returns a numeric value between -1 and 1, which
represents the sine of the angle given in radians.
Because sin() is a static method of Math, you always use it
as Math.sin(), rather than as a method of a Math object you
created (Math is not a constructor).
Examples
Using Math.sin()
Math.sin(0); // 0
Math.sin(1); // 0.8414709848078965
Math.sin(Math.PI / 2); // 1
