Homework for Lecture #4
Bring these to class during lecture 5 to be checked. If you have any questions about how
to do something, bring those, too.
For full credit, you must make a reasonable attempt at answering every question.
You need to show all your work, for all the steps, in a legible and easy-to-follow way.
You also need to staple multiple sheets together, to remove any 'spaghetti edges', and to
make sure that your homework is done in a manner that is professional and presentable.

Keep in mind that for every homework assignment, you should do as many problems as
you need to really have some confidence that you understand the material. If that means
you do more than what’s here, that’s great. While I’d prefer that you do these questions
(just to ensure that everyone has a base level of knowledge), if you want to do other
questions (of the same type as these) instead, go for it.
