Introduction
Functional differentiation means computing or approximating the deriviative of a function. There are several ways to do this:
- Approximate the derivative
by
where
is close to zero. (or at best the square root of the machine precision
.
- Compute the derivative of
symbolically. This approach is particularly interesting for Haskell.

There have been several blog posts on this recently. I think we should gather the information together and make a nice wiki article on it here. For now, here are links to articles on the topic.
