Problem sets will be assigned on a continuing basis every week or two.
Late homework will not be accepted, because I will often use the last half hour of class on the day they're due to go over the solutions. If you can't make a class when a problem set is due, turn it in early at my office.
Cooperation policy: You may collaborate in study groups on the solution of the homeworks. You must, however, write up solutions on your own (not copy). If you do collaborate, acknowledge your collaborators in the write-up for each problem.
You are encouraged not to seek online materials, etc. If you do obtain a solution with help (e.g., through web search or library work), acknowledge your source, and write up the solution on your own.
You must acknowledge in writing any source you use for help.
