Math engine for python/cython. Deep, broad, and fast. Calculus, Cryptography, Differential Equations, Graphics, Dynamical Systems, Geometry, Graph Theory, Linear Algebra, Number Theory, Statistics/Probability, interactives that could make for useful web tools. Only works in Jupyter NB, not Lab :/ This is a mish mash of standard formats/equations I'll likely use to build off of. Lower abstraction than Sympy, but much faster and seemingly broader applications.
