Python math ModulePython math.atan2(y,x)Returns the arctangent of the given y and x coordinate values, atan(y / x), in radians, with the result between -pi and pi.
Python Version: 1.4
Syntax
The syntax of the math.atan2() method is as follows:
math.atan2(y, x)
Parameter description:
- xy -- Required, a positive or negative number.
- yx -- Required, a positive or negative number.
Return Value
Returns a floating-point number representing the arctangent of the y and x coordinate values, with the result between -pi and pi.
Example
The following example returns the arctangent of y/x:
Example
# Import the math package
import math
# Output the arctangent of y/x
print(math.atan2(8, 5))
print(math.atan2(20, 10))
print(math.atan2(34, -7))
import math
# Output the arctangent of y/x
print(math.atan2(8, 5))
print(math.atan2(20, 10))
print(math.atan2(34, -7))
