This is awesome. What a concept, identifying the variables in the equations and providing diagrams to show the geometric meaning of the equations. Really wish wikipedia (or some sort of companion website) would similarly present an explanation of the practical meaning of variables and operators in the heavy math pages so that people with an understanding of algebra could understand the formulaic descriptions in addition to the qualitative descriptions after landing on a random page with heavy math.
Thanks for the feedback and I agree! I'm going to try to create guides for relativity and quantum mechanics. After I finish those, I'll keep expanding into general math topics, so hopefully those will help as well.
Also an FYI - I made a similar guide to linear algebra which you can also find here:
