First edition of an important mathematical textbook. Apostol was an analytic number theorist and professor at Cal Tech. Publisher's description from a later editionL "An introduction to the calculus, with an excellent balance between theory and technique. Integration is treated before differentiation -- this is a departure from most modern texts, but it is historically correct, and it is the best way to establish the true connection between the integral and the derivative. Proofs of all the important theorems are given, generally preceded by geometric or intuitive discussion."
