This math.atan2()
method is used to calculate the arctangent of y/x
, in radians, where x
and y
are coordinates of a point (x,y)
in the cartesian plane.
The value returned by this function is between
-π
andπ
.
math.atan2(y, x)
This method accepts positive and negative numeric values.
y
: the first parameterx
: the second parameterThis method returns a primitive float
value, representing the arc tangent x/y
in radians, between -π
and π
.
This angle
θ
returned by this method is from polar coordinate(r,θ)
.

TypeError
This method will generate an error when we pass integer arguments.
It’s also Python version-dependent.
Python 3: TypeError
: a float is required.
Python 3.8: TypeError
: must be a real number, not a list.
