Math.sin()

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.

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
