What should the Mathematics requirements for Physics degree really be? The usual official requirement is three semesters of Calculus, and then one more combination course which combines some linear algebra and not-too-complicated differential equations. Often the Physics majors, at least for bachelor's degree, take more than that and find some way of using some. If an undergraduate student really wants to be good at Physics, which courses more should or need he do? Why then, are these not listed as the official requirements for the degree?
