Prerequisites

Math 141 or equivalent. It will be ASSUMED that the student is very familiar with the contents of Chapters 1-10 in Calculus with Analytic Geometry, 6th ed., by R. Ellis and D. Gulick! Those chapters contain the material covered in Math 140-141.

Homework Assignments

There are two kinds of homework problems. HOLR-based problems are modifications of those found in the HOLR book. To access these problems, click on the appropriate link below according to your section number.

These problems must be solved using the MATLAB computer package. More information on the HOLR/MATLAB homework may be found in another section of this web page. We note only here that these will be integrated documents combining input, output, graphics, and textual commentary. Problems from B&DiP may be solved either with paper and pencil or with MATLAB, at your discretion. Only the MATLAB homework will be collected and graded!

Exam Schedule

There will be three hourly exams and a final exam. The schedule is as follows:

First Exam:: Thursday, September 23 Exam Data
Second Exam:: Thursday, October 21 Exam Data
Third Exam:: Tuesday, November 23 Exam Data
Final Exam:: Monday, December 13, 1:30-3:30PM.

Quiz Schedule

There will be regular 10-minute classroom quizzes administered in the lecture sessions. The quizzes will occur every Tuesday except for the first week and each week in which there is an exam. The weekly quiz will be admininstered at the START of the period at 9:30 AM -- SHARP -- and will conclude at 9:40, without exception.

Grading Policy

The maximum possible number of points you can score in this course is 750. Your final grade will depend upon the total points you score on the MATLAB homework, the quizzes, three hourly exams, and the final exam, distributed as follows:

Category	Total Points
Homework (HOLR)	200
Quizzes	50
Three Hourly Exams	300
Final Exam	200

Generally there will be no make-up exams for any of the three in-class exams. If you miss ONE in-class exam and if you

have a 6 or better on all but one of the quizzes covering the material on that exam This requirement has been dropped!
earn a C- or better on all the other exams (including the final),

then your score for that exam will be one fourth of the total of your final exam score plus your scores on the other two in-class exams. In all other cases if you miss one or more in-class exams, then your score for each missed exam will be zero.

A complete list of homework assignments and due dates is available. Late homework will not be accepted.
