Math 463 Homework

Homework Policy

Homework assignments will be posted on the course website throughout the semester, and will be assessed as described below. Solution manuals can be found on the course website. Use the manuals carefully, and note that there are mistakes.
Homework assignments are to help you get a better grasp on the material--to learn by doing. I will have the TA grade a selection of your submitted problems for correctness, and if any problems are incorrect you will receive a grade of N (Not Satisfactory). However, you may continue to resubmit problems until you complete them all satisfactorily (S). Your overall homework grade will be the percentage of satisfactorily completed assignments.
