1/1

Each homework problem is worth 5 points, whether it is long or short, easy or hard. Please identify yourproblem sets using the HW number and identify each problem by its specific number. Homework

problems turned in late will have a maximum score of 25%. Note the difference betweenExercisesandProblemsin Ohanian. In addition to assigned problems that are handed in for grading, I will list practiceproblems and exercises that I recommend that you do in order to better understand the material (and dobetter on tests).

All homeworks are due on Thursdays unless you are informed otherwise.

Homework grading rubric:5 pts for all correct and clearly explained.4 pts if the essence of your solution is correct but there is an error or if the explanation is not clear.

3 pts if you have made more than one error or your explanation is a mess2 pts for an incorrect or seriously flawed argument1 pt for handing it in with a statement of the problem that indicates that you understand what the problemis.

0 pts if it is clear that you copied someone elses work.
