*question:*
why did i get different values for the same input?
Because they are not the same inputs.
11 is an integer and 11.0 is a float and Python (along with many
programming languages) treats division slightly differently for
ints and floats. You can bypass this by making your divisor a
float:
######
def f(y):
return (y/5.0)*2*(np.pi)*0.2
##########
Now it will return the same result regardless of int or float.
In Python v3 this is the default behavior
