Using Python to compute the Atan () method of trigonometric functions

The Atan () method returns the inverse tangent of x, expressed in radians.
Syntax

The following is the syntax for the Atan () method:

Atan (x)

Note: This function is not directly accessible, so we need to import the math module and then call this function with the static object of math.
Parameters

• X--This must be a numeric value.

return value

This method returns the inverse tangent of x, expressed in radians.
Example

The following example shows the use of the Atan () method.

#!/usr/bin/pythonimport mathprint "Atan (0.64):", Math.atan (0.64) print "Atan (0):", Math.atan (0) print "Atan": ", Mat H.atan (+) print "Atan ( -1):", Math.atan ( -1) print "Atan (1):", Math.atan (1)

When we run the above program, it produces the following results:

Atan (0.64): 0.569313191101atan (0): 0.0atan (+): 1.4711276743atan ( -1): -0.785398163397atan (1): 0.785398163397
