I am a physics major with a math minor. I only have to take two more math classes after this semester to finish my minor. I'd like to know which classes would be most beneficial for me. I've taken: Calc I Calc II Calc III Diff Eq Linear Algebra Differential Geometry Courses that I can take for my minor: Intro to Analysis Real Analysis I Linear Algebra II Partial Diff Eq Intro to Complex Analysis Numerical Analysis I've been leaning toward Linear Algebra II and Partial Diff Eq. I don't want to be a theoretical physicist and I want to do either Astrophysics or optics.
