**The exam will be in Memorial Hall.****The exam covers sections 2.3, 2.5, 2.7, 3.1-3.3.****CALCULATORS WILL BE PERMITTED, but you will still have to show your work. For example, if I ask you to use calculus to sketch the graph of a function, you will have to show how you computed the derivatives and what you did with them.****The exam questions will be similar (but not necessarily identical!) to the homework questions.****To prepare for the exam, I recommend the following strategy: Get a set of file cards. Using one file card for each homework problem, copy the problem onto the front of the card, along with the section number, and the final answer on the back of the card. Shuffle the cards and choose two from each section. Give yourself one hour to work all of the problems, but do not check your answers during this hour. When you are done, check your answers and find out what you did right and what you did wrong. Consult the homework solutions for the correct answers. Repeat this procedure until you can score at least 90%.**
