Worldwide Differential Calculus
Differential Calculus is the study of instantaneous rates of change; these rates of change are known as derivatives. This book is written by David B. Massey, Ph.D., an award-winning teacher and world-renowned research mathematician, who has been teaching college students for 30 years. He emphasizes intuitive ideas in conjunction with rigorous statements of theorems, and provides a large number of illustrative examples. In the accompanying videos, Dr. Massey lectures on the core material from each section.
- Written by an award-winning mathematics professor with 30 years of teaching experience
- Down-to-Earth exposition, presented as it would be spoken in class
- Completely rigorous definitions, statements of theorems, and proofs
- Technical proofs at the end of each chapter, to avoid disrupting the exposition
- Margin side-remarks and historical references
- Hyperlinked table of contents, index, and cross-references
- Embedded video links to full-length lectures
- Video-solutions to select exercises
- PDF format, compatible with all computers, tablets, and mobile devices
- Low cost in electronic or print form

“Watching the lectures before class was really helpful and allowed me to grasp the concepts better in class.”
“The videos were extremely convenient. They were basically full lectures that could be watched at any time. When I was comfortable with a concept, I could easily skip through it in the video and move on to harder concepts.”
“I watched the videos when I missed class or didn’t understand the topic well enough. The videos supplemented the material sufficiently and well.”
“I liked the writing, especially how the final theorems were boxed so they were easy to find.”
“The calculus book covers a broad range of topics. The writing in the book is very easy to read and conversational.”
“The explanations of each topic were thorough, especially the proofs. It was good to see it explained in theory and application.”
“I love your concept - it has the potential to become a very, very unique look at Calculus within the context of our entire world.”
High School Teacher
“I like the flow of the book. The progression makes sense and it keeps teachers from jumping around from chapter to chapter.”
High School Teacher
“It provides such a cost effective way to provide a textbook to my calculus students.”
“I like the friendly and lecture style presentation of the book.”
“The author has put more thought than other authors into examples and solutions. He does a good job to using examples to motivate mathematical concepts.”
