This is my first time posting in this forum, I am not very familiar with the rules. I am a year 1 physics student, and I had only taken 1 variable calculus( I also know some basic linear algebra, e.g. how to calculate eigenvector in 2x2 situation, don't know Gram–Schmidt process for orthonormalising vectors) . The syllabus is the following Limits, derivatives, linear approximation, curve sketching, L’Hospital’s rule, techniques of integration Because physics need a lot of knowledge of ODE, I am planning to register ODE course from the maths department. The syllabus is the following: methods of explicit solution, linear equations and systems, series solutions, Sturm-Liouville boundary value problems, dynamical systems and stability, applications to mechanics, electrical networks and population of species. Can you guys give me some advice that, if I have the foundation to take this course. What further mathematics I have to learn before ODE?
