Using explicit expressions for analytical derivatives often results in much faster code than using symbolic math. However, coding expressions for analytical derivatives is sometimes an error-prone process.

This tool makes it easy to test analytical derivatives up to order three against numerical derivatives, for functions of one or two variables.
