Most Pertinent Topics; Calc 2 --> 3 Heyo, Posted here a while back looking for books, as I was planning to study over spring and summer before I registered at a CC. Now it's time to pick my classes for my first semester. So, I was wondering which topics in calc II I should be reviewing before I take calc III. Calc II bored me, because it was like calculus I with a good deal of trig. and harder integration problems, so I decided to try my hand at linear algebra instead of calc III.
