Python atan2 – Find Arctangent of the Quotient of Two Numbers

To find the arctangent, or inverse tangent, of the quotient of two numbers, we can use the Python atan2() function from the math module.

import math

math.atan2(x,y)

In Python, we can easily use trigonometric functions with the Python math module. The Python math module allows us to perform trigonometry easily.

With the Python math module, we can find the arctangent of a number easily.

Python gives us the ability to find the arctangent of the quotient of two numbers, where the two numbers represents the coordinates of a point (x,y). To find the arctangent of a the quotient of two numbers, we use the math atan2() function.

Below is the Python syntax to find the inverse tangent of the quotient of two numbers.

import math

math.atan2(x,y)

The inputs to the atan2() function must be a numeric values. The return value will be a numeric value between -pi and pi radians.

import math

print(math.atan2(5,1))
print(math.atan2(0,0))
print(math.atan2(-3,7))

#Output: 
1.373400766945016
0.0
-0.40489178628508343

Finding the Inverse Tangent of a Number in Python

If you are just looking to find the inverse tangent of a number in Python, you can use the regular atan() function in Python.

Below is the Python syntax to find the inverse tangent of a number.

import math

math.atan(x)

The input to the atan() function must be a numeric value. The return value will be a numeric value between -pi/2 and pi/2 radians.

import math

print(math.atan(5))
print(math.atan(0))
print(math.atan(-3))

#Output: 
1.373400766945016
0.0
-1.2490457723982544

Hopefully this article has been beneficial for you to understand how to use the math atan2() function in Python to find the arctangent of the quotient of two numbers.
