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