Please use pencil, indicate who you work with (or if nobody, then write that instead), and leave space for comments!
Homework will be assigned on Thursday and be due in class on Thursday of the following week, or at the latest at 5:00PM on that day in my mailbox.
Every assignment is worth 15 points.
Assignments that are not picked up in class the day I return them will be kept in my office. Please stop by to pick up your old assignments.
IMPORTANT: If you use ANY outside help on an assignment, then you must acknowledge this. For example if you talk to anybody but me about the assignment write down the name and problem number. Similarly if you used the internet, computer programs or books other than our textbook. Failure to acknowledge using the work of somebody else is plagiarism and will be dealt with harshly.
The only theorems that you may use as auxiliary results in the solution of a problem are those that were proven in class or can be found in a section of the textbook that we have covered. You should always properly quote by giving the correct reference to the textbook.
You can use MATLAB on your assignment, but beware:
- Always clearly indicate when you use MATLAB. Write something, at least the word MATLAB with a circle around it, and ideally an explanation of what you had MATLAB do. If I can't follow how you use MATLAB, then I may deduct points from your homework.
- On exam 1 you will not be allowed to use MATLAB. You should make sure that you know how to do important things (like solving systems of equations, multiplying matrices, finding determinants) by hand.
- On exam 2 you will be allowed to use MATLAB, so make sure you know how to use MATLAB.
Please STAPLE your homework and write NEATLY. If one of the pages of your assignment gets lost, or I can't read something it's YOUR problem. I may decide to deduct points for sloppy work.
The one or two lowest homework scores will be dropped.
