I am trying to calculate the inverse of tan in python, but it does not give me the correct value, for example, if I were to do the inverse tan of 1.18, math.atan(1.18)

>>>math.atan(1.18)
0.8677

However, the correct answer is 49.720136931. What is the correct way to do than?

math.atan(x) returned in radian, if you want degree, convert it using math.degrees(x)

Converts angle x from radians to degrees.

>>> import math
>>> math.degrees(math.atan(1.18))
49.720136931043555
