Calculus Made Even Easier: An Infinitesimal Differential Approach

This book is intended for science or engineering majors who use calculus and others who are required to take calculus but do not understand limits. This is calculus without limits. It is a non-rigorous infinitesimal differential approach to calculus. It should foster better operational skills with calculus problem solving because it involves algebraic operations on differentials based on a more intuitive understanding of their meaning than calculus based on limits. These are the methods that were originally conceived by G. Leibnitz over 300 years ago and have been used successfully by scientists and engineers ever since. It is written in the spirit of "Calculus Made Easy" written by S. Thompson. He wrote his book in 1910 but this book makes calculus, I believe, even easier. This is not a textbook. Examples are given to illustrate concepts but there are no exercise sets at the end of a unit. This book should be used as a supplement.
