 Homework 8Comments
 Problems are taken from the textbook unless otherwise noted.
 For full credit, provide context for each problem, show all calculations, and justify all answers by providing enough comments to explain your reasoning.
 You will lose a significant amount of credit if you do not provide context, calculations, and justifications for a problem.
 Numbers and/or algebra by themselves are not enough. A correct answer with no justification will be worth no more than half credit, and sometimes much less than that.
 Precision is very important. You cannot skip steps, make guesses, or use flawed logic. Any of these things can lead to incorrect answers.
 Homework assignments must be very neatly written or typeset
(e.g. using Word or OpenOffice).
 You must indicate any assistance/collaboration you had on an assignment as specified on the Policies page.
