Math.sin()

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

Try it

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).

Examples

Using Math.sin()

Math.sin(-Infinity); // NaN
Math.sin(-0); // -0
Math.sin(0); // 0
Math.sin(1); // 0.8414709848078965
Math.sin(Math.PI / 2); // 1
Math.sin(Infinity); // NaN
