# The Mathematical Functions Grimoire

Pre-alpha version

Welcome! The Mathematical Functions Grimoire (Fungrim) is an open source library of formulas for mathematical functions. Fungrim currently consists of 261 symbols (named mathematical objects), 1105 entries (definitions, formulas or tables), and 41 topics (listings of entries). All data in Fungrim is represented in symbolic, semantic form designed to be usable by computer algebra software. Fungrim is also fully viewable online, with a permanent ID and URL for each entry, symbol or topic. This is one formula entry:

$\zeta\!\left(s\right) = 2 {\left(2 \pi\right)}^{s - 1} \sin\!\left(\frac{\pi s}{2}\right) \Gamma\!\left(1 - s\right) \zeta\!\left(1 - s\right)$
