Textbook and WebAssign
The textbook for all levels of Calculus (1, 2, and 3) is titled “Calculus” by Laura Taalman and Peter Kohn. There is only one edition (the 1st).

If you purchase the textbook from the Trinity College Bookstore, the hardcover text will come with an “access code” to enroll in WebAssign, which will be valid for all levels of Calculus.
If you purchase the book elsewhere, it very likely does NOT come with access to WebAssign, which will need to be purchased separately. The following PDF has information about the various options for purchasing WebAssign access with or without an eBook. Note: you will only have access to the eBook during the semester, and it is NOT a PDF that can be downloaded.
Desmos
Desmos is an incredible free online graphing calculator that you can access from any web browser. There is also an app for iOS and Android phones and tablets. This graph introduces you to some of the things Desmos can do. If you create a free account, you can save graphs that you work on. If you utilize Desmos effectively, you can save large amounts of time on certain problems that you might use a graphing calculator for.
The Padlet below collects all of the Desmos links in one place.
