JavaScript - Math.atan() Method
The JavaScript Math.atan() method returns arc tangent of a value. The returned value will be in the range -𝜋/2 through 𝜋/2.
Syntax
Math.atan(x)
Parameters
x |
Specify the value. |
Return Value
Returns the arc tangent of the value.
Example:
In the example below, Math.atan() method is used to find out the arc tangent of a given value.
var txt; txt = "Math.atan(0.5) = " + Math.atan(0.5) + "<br>"; txt = txt + "Math.atan(1) = " + Math.atan(1) + "<br>"; txt = txt + "Math.atan(2) = " + Math.atan(2) + "<br>";
The output (value of txt) after running above script will be:
Math.atan(0.5) = 0.4636476090008061 Math.atan(1) = 0.7853981633974483 Math.atan(2) = 1.1071487177940904
