I'm trying to decide whether to take a second semester of ordinary differential equations. My school's physics degree requires you to have differential, integral, and vector calculus along with a semester of ODEs. I have had all of the above along with linear algebra and a semester of PDEs. Later I plan on taking a year of numerical analysis, I'm also in computer science, not that num analysis isn't useful in physics, and maybe a semester of complex analysis. Should I take another semester of ODEs?
