The three exams, E1, E2 and E3 will be graded out of 100. They will be combined in the following way to obtain a total point total out of 100:

S1 := 0.3*E1 + 0.3*E2 + 0.4*E3 - 0.3*min(Ei: i=1..3) + 0.3*E3

S2 := (0.90-n*0.02)*S1 + (.10+n*0.02)*HW

S := max(S1,S2)


The score S out of 100 will be translated into a letter grade of A, B, C, D, F (with plus and minus shadings) in a way that is not stricter than the following table:

Numerical Range Letter Grade
[80,100] A
[65,80) B
[50-65) C
[40-50) D
[0,40) F


It is not likely that "curving" will be applied. There is not much point in asking about this. That is because nothing will be decided until after the final exam. However, it is prudent to assume that there will be no curving. I will try to write exams with enough routine problems that at least a B- is likely.

Calculators are NOT allowed on exams.

Use of a prohibited calculator at an exam is an academic integrity violation that will be referred to the Academic Integrity Committee.



3. Text

Elementary Linear Algebra, Eighth Edition, Bernard Kolman and David Hill

We should cover most of the book. No other book is required. I have been asked whether earlier, cheaper editions would suffice. The answer is "almost certainly", provided that you are willing to adjust to the differences in exercises.

5. Software

Software is not required for this course. However, it is a great advantage to know a package so that you can check your manual work. I recommend MAPLE. Materials for this course will be distributed as MAPLE files. You can use the copy of Maple in the Eads computer lab to open and view the distributed files. The release there (5.1) is about five years out of date. The student edition of the current version, Release 8 can be purchased at the book store for around the price of the course textbook. It is a better value.



It may be possible to view the files using an old demo. However the demo has no "Help" facility and lacks most working functionality.

6. Assignments

In the first assignment that covers a topic you must complete the computation "as if by hand." If you use software then that means that you must use the software step-by-step to obtain the answer. For example, the first assignment is about solving linear systems. The software package Maple has a one line command, linsolve(A,b) to solve the linear system Ax=b. If you use Maple in the first assignment then you may not call on linsolve. You must use the step by step commands such as addrow, mulrow, and swaprow. If you have to solve a linear system in any later assignment then you may feel free to call on linsolve.

You may use any other software package but help is available only for Maple. Reference sheets for using Maple are given in the assignments. Download them from this directory and place them in a directory with your homework assignment. When you do the assignment, clicking the hyperlink in the assignment will open up the reference worksheet.

Whatever the software that is used you must show every step of a computation but you need not show the result of every step. In Maple that means using the colon as a (silent) command terminator for every step up to the last. The final answer is then displayed using the semicolon terminator. No need to sacrifice a stand of trees every assignment.

Maple files (worksheets) are not intended for viewing with a browser. You must open them with a Maple reader. Your system may be configured to launch such a reader when you click on a link to a *.mws file. If not, then just save the file. For, example, if you are using Netscape from a Windows platform, then right-click on a worksheet link and choose the "Save As" option. Because Maple worksheets are plain text files, browsers will display them as text. However, the characters will have no meaning to you. If this happens, ignore the display, and save the downloaded file (preferably with the Maple worksheet mws extension). Then use Maple to open up the file that you have saved.
