Math.cos()
syntax: |
Math.cos() |
where: |
x - an angle, measured in radians.
|
return: |
number - an implementation-dependent approximation of the cosine of the argument
|
description: |
The argument is expressed in radians. Returns NaN if x cannot be converted to a number. In order to convert degrees to radians you must multiply by 2pi/360.
|
example: |
//The cosine of x is returned //in the following function: function compute_cos(x) { return Math.cos(x) } |
