Python math.atan2()

The math.atan2() function in Python takes two numeric values representing a point (x, y) and returns a float that represents the arc tangent of y divided by x. The resulting value is in radians and ranges from -π to π.

Syntax

math.atan2(y, x)

• y: A numeric value representing the y coordinate of the point.
• x: A numeric value representing the x coordinate of the point.

Note: The function takes the y-coordinate (y) as the first parameter and the x-coordinate (x) as the second.

Example

In the example below, the math.atan2() function is used to return the arc tangent of a point (5, 6):

import math

print(math.atan2(6, 5))
