Welcome

Welcome to the website for users, students, and teachers of Calculus: The Language of Change. We hope you will find the tools and resources here stimulating and valuable.

We use this site ourselves. We’ve bookmarked it. When we have a complicated problem and we need to see some graphs or we need to know the consequences of a set of differential equations, we click on “Software Tools.” When we’re looking for a fresh problem or an unusual application, we look through the “Additional Real-World Applications” section.

We hope to expand this website with your contributions. Our textbook users have various backgrounds and interests. We would love to see your favorite contexts, problems, and adventures. Calculus is a language. When we wrote our book, we started a conversation in that language. We’re looking forward to hearing from you!

Please send your ideas to our editor, Tim Anderson and he will forward them to us. We will post your suggestions in an “Online Community” section.

All the best,

David Cohen
