In this article, I will introduce how to use the Math.cos() method in JavaScript.

The Math.cos() method

The Math.cos function returns the cosine of the angle specified as an argument.
The angle is specified in radians.

The syntax is below.

Math.cos(x)

x: The angle in radians

If you want to use angles in degrees, you need to convert them to radians.

Math.cos(degrees*(Math.PI/180))

For example, to get cos30°, cos45°, and cos60°:

Math.cos(30*(Math.PI/180));
Math.cos(45*(Math.PI/180));
Math.cos(60*(Math.PI/180));
