Special Functions

Most places that talk about special functions usually consider functions like: Airy, Bessel, Chebyshev, and Lagendre, but here we will consider a different class of special funcitons. Instead of considering special functions that are the solutions of differential equations, as most of those just mentioned are, we will be considering functions such as xx or the iteration of such functions. The function xx is notoriously difficult to iterate, expecially in a smooth manner. For more information about continuous iteration, click on the iteration tab above.

Function Mnemonics

Unlike the functions that are represented by single letters (like f or W) or perhaps 3 letter lowercase mnemonics (like exp, log, sin, cos, ...), this website uses a wide variety of two letter uppercase mnemonics. Here is a short explaination of each term, and a link to where to find more information about it.
