For anyone out there looking to get a good solid grasp of mathematics for Physics the following is a few books i would highly recommend. - A First course in Calculus by Serge Lang - Calculus of several variables by Serge Lang - The Calculus Lifesaver: All the Tools You Need to Excel at Calculus by Adrian Banner - Ordinary Differential Equations by Morris Tenenbaum, Harry Pollard - Partial Differential Equations for Scientists and Engineers by Stanley J. Farlow - Div, Grad, Curl, and All That: An Informal Text on Vector Calculus by H. M Schey Careful study of these texts in my view will most certainly be worth it for anyone wishing to progress in Physics at undergraduate and graduate level. I am sure there are many other tests out there and would be interested to hear recommendations. I think these books strike a good balance between application and theory. Cheers David.
