Hello, I'm a first year Physics student. I've decided to take on mathematical methods and be as thorough with it as I possibly can. I am looking for books that cover vector calculus, Orthogonal transformations, tensors, curvilinear co-ordinates, index notations and the dirac-delta function in details. I am currently using: Mathematical Methods for Physicists by Boas, Mathematical Methods for Physicists by Arfken and Weber (my favourite till now), Vector Analysis by Spiegel Are these enough to get me through? If you have other books in mind that may be helpful, please mention. Thank you.
