Title: suitable historical perspective
Review: Calculus was discovered by Newton and Liebniz in the 1600s. They used a method of infinitesimals to derive their results. To this day, infinitesimals are used as an intuitive explanation of calculus, to scientists and engineers. But to many mathematicians, there is an unsettling lack of rigour.Grabiner explains how this state of affairs from the 1600s persisted until Cauchy [and others] came along. He found an epsilon -delta approach that permits a strict derivation of theorems. This book should give an appreciation of that approach, in a suitable historical perspective.
