Good lord, I hate Stewart's book on Calculus. I had to buy two editions of his book because they changed the required edition between the semesters I took Calc 2 and Calc 3. Forunately most of my teachers have been very good after text books especially in the computer science faculty, given that most if not all of what they teach can be found online for free. My stats professor even made his own textbook which covered everything in the class, with example problems, and sold it for $20.
