A Course of Modern Analysis (colloquially known as Whittaker and Watson) is a landmark textbook on mathematical analysis written by E. T. Whittaker and G. N. Watson, first published by Cambridge University Press in 1902. (The first edition was Whittaker's alone; it was in later editions with Watson that this book is best known.)The book is notable for being the standard reference and textbook for a generation of Cambridge mathematicians including Littlewood and G. H. Hardy.
