## Python math.atan()

math.atan() function returns the inverse tangent of given number.

The return value is angle in radians, and lies in [-pi/2, pi/2] radians.

### Syntax

The syntax to call atan() function is

``math.atan(x)``

where

### Examples

In the following example, we find the inverse tangent of 1.732 using atan() function of math module.

Python Program

``````import math

x = 1.732
result = math.atan(x)
Run Code Copy

Output

``atan(x) : 1.0471848490249274 radians``

We can convert the returned radians into degrees using math.degrees() function.

In the following example, we find the inverse tangent of 1.732 using atan() function and convert this returned radians to degrees.

Python Program

``````import math

x = 1.732
result = math.atan(x)
result = math.degrees(result)
print('atan(x) :', result, 'degrees')``````
Run Code Copy

Output

``atan(x) : 59.99927221917264 degrees``
