The following document contains the homework assignments given in the Spring of
2010. These are not the assignments that you are being given for homework, but
you might want to do the suggested problems in advance or just after a section to
test your comprehension of the material. I am providing this so you are more aware
of the types of problems and hence the concepts that I stress in teaching this course.
