How to study:
First, flip through my notes, making sure you understand the
examples presented. Look at the past couple homework
solutions, and also look at previous homework questions on
this material. Practice these problems. Finally, flip through the

sections I mentioned above. Keep in mind that I may not have
covered everything in these sections.
