Math 90: Week 4

It was quiz-day!

The class did pretty well on the quiz. I wrote the quiz, and I’m pleased with the skill-level demonstrated. The average was about a 77%, and the median was an 80%. (For stat-witty folk, this means that the lower scores were somehow ‘lower’ than the average scores).

Anyhow, the solutions to the day’s problems and the quiz are below the fold:

Math 90: Week 3

First and foremost: There is a quiz next week during recitation! What is it over? you might ask. Any material from any of the first three homework sets (i.e. all material covered in lecture up to Tuesday September 25th) will be fair game.

Someone asked me in office hours this week: “Why do you end your posts with something about a ‘fold’?” I mention a ‘fold’ to indicate that there is more to the post, and that you should click on the name of the post or on the not-so-subtle (more…) at the bottom for the rest. Fittingly, the rest is after the fold:

Math 90: Week 2

Yes, although it’s the second week of class, this is after the first recitation.

In addition, I can now announce my office hours. They are from 7-8PM on Monday in Kassar House room 105 and 12:30-1:30PM on Wednesday in my office (number 18, my name is on the door) in the basement of the Kassar House. To get in the building on Monday, you should look at the MRC page, and in particular at this (shaky youtube) video.

After my evening recitation, I’ll post up the problems I gave out in class and their solutions. Please feel free to ask any questions you want here. The details are included after the fold:

Math 90: Week 1

This is a post related to how I plan to conduct my [Math 90] TA sessions. I would like to use this space as a supplement to the class work. Each Tuesday night, after my recitations, I will post my worksheets and their solutions under a new page. That page will serve as a comment-forum for for any questions students may have over that week. I will answer any comments posted here periodically throughout the week. It is also possible I may post additional, supplementary materials here if I feel it necessary.

You can write mathy things on this forum using the $\LaTeX$ formatting language. A bit more on that here, except that to product inline formulas with $\$ \text{latex (code)} \ (dollar sign, the word latex, the code, followed by a dollar sign). For example, we’ll be doing things like $\displaystyle \int_0^1 x^2 dx$ and $\displaystyle \sum_{n = 1}^N \left( \frac{1}{N}\right)f\left( \frac{n}{N}\right)$ in this course.
