Hi all,
Let's say I have a function defined as follows:
>>> def f(x):
return x**2
I can differentitate this function:
>>> from sympy import Derivative
>>> Derivative(f(x), x)
Derivative(x**2, x)
>>> Derivative(f(x), x).doit()
2*x
>>> Derivative(f(x), x, x).doit()
2
..find the limit:
>>> from sympy import limit
>>> limit(fx, x, 0)
Traceback (most recent call last):
File "<pyshell#114>", line 1, in <module>
limit(fx, x, 0)
NameError: name 'fx' is not defined
>>> limit(f(x), x, 0)
0
Is there any specific reason I would want to subclass Function and
then override the relevant methods unless I am expecting that my code
would be expected to have the .diff() method or any other methods for
example?
Thanks,
Amit.
