The Mathematics Companion - Mathematical Methods for Physicists and Engineers, 2nd Edition

Updated and expanded with new topics, this second edition presents the essential core of mathematical principles needed by scientists and engineers. It uses a unique and educational approach that is the signature style of the author’s companion books. Starting from the basic concepts of trigonometry, the book covers calculus, differential equations, and vector calculus. A new chapter on applications discusses how we see objects "mathematically" with the eye, how quantum mechanics works, and more.
