Online courses or video lectures on John Hubbard's textbook covering Vector Calculus, Linear Algebra, and Differential Forms are sought after. Ted Shifrin's book, "Multivariable Mathematics," has associated lectures available on YouTube. There is mention of a course at Cornell that may be based on Hubbard's work, although the link is currently unavailable. Users are encouraged to explore these resources for further learning. The discussion highlights the need for accessible educational materials in advanced mathematics.
