Trying to learn to solve partial differential equations. These relate rates of functions of multiple variables and are used for describing the dynamics of a system, and their solutions make predictions about how the system evolves. - by hand - without any experience writing meaningfully heterogenous proofs - without being able to construct any relevant equations from models - without a good understanding of the origin of Bessel or Airy series - without having lists of criteria committed or understanding of when series solutions are called for - without understanding solving systems of differential equations - without any significant motivating application to strive towards at the time - without considerable practice teaching myself things, since the lectures felt like a kitchen knife piano ballet https://youtu.be/x93DsA7UHhs https://youtu.be/x93DsA7UHhs I eventually broke down and sat in the library for hours at a time making a handwritten copy of the exposition of the textbook, hoping something would stick. I was passed.
