The first midterm will be Friday, Jan. 30, during class. Here is a sample exam. Here are the solutions. This exam covers up to and including Section 2.1. The exam will consist of eight problems of which you will do five. Each will be worth 10 points for a total of 50. We will be grading on how well you put an argument together, not just how well you understand the concepts. You may cite any Theorem that we have covered in class or that has appeared in the book, but just be clear on when you are doing so. Please see me or Eamonn to discuss exactly what constitutes a complete proof. The sample exam problems will not be the same as the exam problems, but they will be of the same format and difficulty.

Here is the first midterm, and here are the solutions.

Here is the second midterm, and here are the solutions.

The final exam is Monday, March 16, 2009, 11:30 AM - 2:30 PM in MS 6229. Here is a practice final, and here are the solutions. The real final will have 15 questions, of which you will choose 10. It will cover all sections of the book from which I have assigned homework. However, the sections covered since the second midterm will be more heavily emphasized.

3/16/09: Congratulations, you're done with Math 115A! Here are the final exam solutions.

3/16/09, 10 PM: Oops, there's a little typo in the solution to problem 15. It should read: -(t+1)(t^2+1), not -(t+1)(t^2+t+1).
