atan2 of number python

The atan2() function in Python is used to return the arc tangent of two variables y and x. It is a mathematical function and is defined as follows:

atan2(y, x)

Where y and x are the two variables whose arc tangent is to be calculated. The function returns the arc tangent of y/x in radians.

Syntax

The syntax for atan2() function is:

import math

math.atan2(y, x)

Here, math is a module in Python that provides access to the mathematical functions, and y and x are two variables.

Parameters

The atan2() function takes two parameters:

  • y: This is the first parameter and is the numerator of the fraction. It is a mandatory parameter and must be a numeric value.
  • x: This is the second parameter and is the denominator of the fraction. It is also a mandatory parameter and must be a numeric value.
Return Value

The atan2() function returns the arc tangent of y/x in radians. The value returned is a float.

Example

Here is an example program that demonstrates the use of the atan2() function:

import math

y = 3.0
x = 5.0

print("The arc tangent of {}/{} is:".format(y, x), math.atan2(y, x))

Output:

The arc tangent of 3.0/5.0 is: 0.5404195002705842
Conclusion

The atan2() function is a useful mathematical function in Python that can be used to calculate the arc tangent of two variables y and x. It returns the arc tangent of y/x in radians and is part of the math module in Python.
