List of derivatives and integrals in alternative calculi

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). Interested readers are encouraged to improve the table by inserting citations for verification, and by inserting more functions and more calculi.

Table

In the following table $\psi(x)=\frac{\Gamma'(x)}{\Gamma(x)}\,$ is the digamma function, $K(x)=e^{\zeta^\prime(-1,x)-\zeta^\prime(-1)}=e^{\frac{z-z^2}{2}+\frac z2 \ln (2\pi)-\psi^{(-2)}(z)}$ is the K-function, $(!x)=\frac{\Gamma(x+1,-1)}{e}$ is subfactorial, $B_a(x)=-a\zeta(-a+1,x)\,$ are the generalized to real numbers Bernoulli polynomials.
