Fall 2012: Math 52 Class Notes

Caveat emptor: These notes will not exactly match what we talked about in class, although it will be close. There may be errors in these notes. Use at your own risk.

Same goes for homework solutions. There may be errors, but hopefully the solutions will give you the idea of what is correct. They may also be taken as examples for the level of detail which would get you full credit.

I've tried to note the important dates for the class here too. See the main course website for the homework assignments and confirmation of the dates of exams, due dates, etc.
