Complete all the problems in each section of the textbook as we go through them, as well as any other problems assigned in class. I will assign certain problems to be handed in; they will be due on the Monday of the following week. Although you may (and should) work together with your class mates, such cooperation should NOT include exchange of written material. The solutions you hand in have to be your own.
