Math.sin()

The Math.sin() function returns the sine of a number in radians.

Syntax​

Math.sin(x)

Parameters​

  • x
    • : A number representing an angle in radians.

Return value​

The sine of x, between -1 and 1, inclusive. If x is Infinity, -Infinity, or NaN, returns NaN.

Description​

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).
