Homework

There are two different textbook options you may choose in order to complete your homework. You may choose either

• Gilbert Strang and Edwin Herman’s?Calculus Volume 1 and Calculus Volume 2
• James Stewart’s?Calculus: Concepts and Contexts, 4th Edition

Select homework sets are provided below for either option you choose. The homework prompts listed are a starting point to practice the material we learned in class (or from the videos). Some people may feel they need more practice after working through these prompts, and that is great to have that self-awareness! In this case, try some of the even prompts between the assigned odd ones.
