**Review for exam 1**

The Math 2243 exam 1 will be held in your recitation sections on Thursday October 3, in your usual room. It is on sections 1.1-1.5, 2.1-2.4, 3.1 from the book.

Here are some extra questions which I have selected to help you with review for exam 1. These questions are intended to help, not to be a list of things which, by implication, you should or should not know. I have tried to find a question for each important topic, but I may have missed some out. For some topics there is more than one question. You should still know topics if I have missed them out.
