There are many alternatives to the classical calculus of Newton and Leibniz; for example, each of the infinitely many non-Newtonian calculi. Occasionally an alternative calculus is more suited than the classical calculus for expressing a given scientific or mathematical idea.
The table below is intended to assist people working with the alternative calculus called the "geometric calculus" (or its discrete analog).
In the following table;
is the digamma function,
is the K-function,
is subfactorial,
are the generalized to real numbers Bernoulli polynomials.
