LaTeX CHEATSHEET:

Office hours:  the official office hours for this class are following each lecture. However, you are very welcome to make an appointment and come ask questions, make comments, or just chat. You can also try showing up at my door anytime. But I might tell you to come back at another time if I am immersed into something else.

The tables of the law for this class are contained in the following document:
Syllabus

Homework:  math math is not a sport for bystanders. Getting your hands dirty  is important  to make sure that things sink in and you are not just spending a semester assisting to my creative rambling. Homework will be due pretty much every Friday (but see below for the up-to-date information). I will NOT grade all the problems I assign. If one of the problems you feel unsure about doesn't get graded, please don't go: "Whew! Lucky one!" but rather come ask me about it. The point is you understanding, not pretending to!!

READ CAREFULLY!! In fact, here is the homework grading policy. For every assignment, you are supposed to write up all problems. However you need to identify two questions: the one that you feel have done best on (which will be graded), and the one where you feel you have done worst on (which will be looked at and commented but not graded). This is supposed to force you to self-evaluate your own understanding, and to maximize the efficiency with which I can give you the most needed feedback.
