Python Number atan() Method
Description
Python number method atan() returns the arc tangent of x, in radians.
Syntax
Following is the syntax for atan() method −
atan(x)
Note − This function is not accessible directly, so we need to import math module and then we need to call this function using math static object.
Parameters
x − This must be a numeric value.
Return Value
This method returns arc tangent of x, in radians.
Example
The following example shows the usage of atan() method.
#!/usr/bin/python import math print "atan(0.64) : ", math.atan(0.64) print "atan(0) : ", math.atan(0) print "atan(10) : ", math.atan(10) print "atan(-1) : ", math.atan(-1) print "atan(1) : ", math.atan(1)
When we run above program, it produces following result −
atan(0.64) : 0.569313191101 atan(0) : 0.0 atan(10) : 1.4711276743 atan(-1) : -0.785398163397 atan(1) : 0.785398163397
