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.

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.

Scripta: this is an essential requirement for this course. You must read the book ahead of the lectures and help me create lectures that are maximally useful for you.

Go to http://www.scripta.io

Log in with the email linear@scripta.io, with the password I have sent you all via email. Click on the notebook Math 469, Spring 2016. You at this point should have permission to read and write on the notebook. On the up/right side of the window you will be able to click on Reader (to read) or Editor (to edit). The following cheatsheet tells you about the basic syntax to write on the notebook. For any questions, comments, tips and especially to pass on feedback or problems about scripta, feel free to contact Jim Carlson, the developer of this platform, at jxxcarlson@icloud.com




 

Exams: There will be one assessment exam, two midterms and a final.  These dates might change, so please check occasionally. If dates change I will also mention it in class, of course.
