Status: Accepted Owner: asmeurer Labels: Type-Enhancement Priority-Medium New issue 1620 by asmeurer: Allow derivatives of unknown functions evaluated at a point http://code.google.com/p/sympy/issues/detail?id=1620
Most CAS's let you represent things like f(0), f'(0), f''(0), and so on, but SymPy only has support for the first. We should enable an option in the derivative of a function evaluated at a point. I don't know what the best syntax would be, probably some argument to diff, like point = 0, or point = (1, 2, 3) for something like f'(1, 2, 3). Not much would need to be implemented. You just need a way to access the point in the Derivative class and Derivative needs to know to subs the point if it is evaluated. -- You received this message because you are listed in the owner or CC fields of this issue, or because you starred this issue.
