                                Midterm 1 Solution
                                Midterm 2 Solution

Quizzes:  A short quiz will be given at the beginning of class every Thursday (excluding September 9th and October 14th).  These quizzes will generally consist of one or two short problems on the material presented in the previous two classes.  Please do not arrive late to class.  These quizzes will usually last for the first 10 minutes of our time, so if you come to class too late, then you will not have time to complete or possibly even begin the quiz.  Make-up quizzes will not be given, even in the case of medical absence.  At the end of the term, I will drop the lowest quiz score from your grade. 

                        Quiz 1 Solution,   Quiz 2 Solution,   Quiz 3 Solution,   Quiz 4 Solution,   Quiz 5 Solution,   Quiz 6 Solution,   Quiz 7 Solution,   Quiz 8 Solution

Webwork Homeworks:  Click here to access.  Use your CWL to login.  Webwork is due each week at 11:59 p.m. on Tuesdays.  The intent of homework is to help you learn the material, and therefore it should be done while you are studying.

Course-Common Homework to Hand-in:  Weekly problem sets will be posted on the Math 104 common site.  See the common site for more information.  This homework is due at the beginning of class each Thursday, before we take the quiz.  You can pick up your graded homework assignments anytime after class the Thursday after you hand it in. Come by my office in AA 138; there will be a box outside my door where you will find the graded assignments. Take only your assignment.

                                                (optional) Hand-in Homework #10, due Thursday, December 2nd;    ---    Hand-in Homework #10 Solution
                                                (optional) Hand-in Homework #11, due Thursday, December 9th;    ---    Hand-in Homework #11 Solution
