Math.cos( ) In JavaScript

The Math.con() function in Javascript is used to return the cosine of a number.
The Math.cos() method returns a numeric value between -1 and 1, which represents the cosine of the angle given in radians. The cos() is a static method of Math, therefore, it is always used as Math.cos(), rather than as a method of a Math object created.

Syntax:

Math.cos(value)

Parameters: This function accepts single parameter which is a number given in radians.

Returns: The Math.cos() function returns the cosine of the given numbers which range from -1 to 1.

Examples:

1. When zero is passed as a parameter.
