The Jacobian meets Robespierre
Doodle for Mathober Day 23: Jacobian. Which, of course, made me think of Jacobins...

Test functions and [tempered] distributions require the notion of topological vector space … distributions can be traced back to Green's functions in the 1830’s to solve ordinary differential equations … the 1936 work of Sergei Sobolev on hyperbolic PDE’s.
Laurent Schwartz introduced the term "distribution" by analogy with a distribution of electrical charge, possibly including not only point charges but also dipoles and so on.
tempered distribution
topological vector space
(^ if there is a dipole, there must be a notion of subtraction, hence the need for a vector, and to speak of this very conceptually, use a TVS)

Drawing in 3D is very hard 😥
A blog about mathematics.
Updated Multi-Variable Calculus! I finished the brief review of single-variable calculus! Although the notes for multi-variable calculus will not really have much to do with this review, it is important to know basic differentiation, integration, and parametrization!
**I also added some notes from Linear Algebra since vectors and properties of vectors will be used a lot in multi-variable calculus!
studying over break!
(sidenote: how come these pics only look clear when you click on them and zoom in? can someone help :/)
