Calculus Made Easy has been a classic introduction to the subject ever since it was first published by Silvanus P.Thompson in 1910. In the first major revision of the text since 1946, Martin Gardner - the 'Mathematical Games' columnist for Scientific American and author of over 50 books and innumerable articles - has thoroughly updated the text to reflect recent developments in method and terminology, written an extensive preface and three new chapters, and added more than 20 recreational problems for practice and enjoyment. He has transformed this classic primer into a modern masterpiece that explains the timeless concepts of calculus in a contemporary and user-friendly voice.
