Python3 atan2 () function
description
atan2 () Returns the arctangent of X and Y coordinate values.
grammar
The following is the syntax atan2 () method:
import math math.atan2(y, x)
Note: atan2 () is not directly accessible, you need to import math module, and then call the method by math static objects.
parameter
- x - a value.
- y - a value.
return value
Returns the arctangent of X and Y coordinate values.
Examples
The following shows an example of the use of atan2 () method:
#!/usr/bin/python3
import math
print ("atan2(-0.50,-0.50) : ", math.atan2(-0.50,-0.50))
print ("atan2(0.50,0.50) : ", math.atan2(0.50,0.50))
print ("atan2(5,5) : ", math.atan2(5,5))
print ("atan2(-10,10) : ", math.atan2(-10,10))
print ("atan2(10,20) : ", math.atan2(10,20))
After running the above example output is:
atan2(-0.50,-0.50) : -2.356194490192345 atan2(0.50,0.50) : 0.7853981633974483 atan2(5,5) : 0.7853981633974483 atan2(-10,10) : -0.7853981633974483 atan2(10,20) : 0.4636476090008061
