I have these two textbooks: Mathematical Methods in the Physical Sciences https://www.amazon.com/Mathematical...ences-Mary/dp/0471198269/?tag=viglink20267-20 And Elementary Linear Algebra https://www.amazon.com/Elementary-L...m_hrd_title_0?_encoding=UTF8&qid=&sr= Which should I begin with? And for the linear algebra textbook, is it all useful for a physicist? I mean, should I work through it all? EDIT: I think I should mention that I finished all calculus courses, along with ODE and PDE courses. A lot of the material in the first book is already familiar.
