Homework from Lecture #5
Bring these to class during lecture 6 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.
