# Math 311 - Spring, 2018

Note:The notes are often incomplete, I haven't written up notes on all the topics, and the notes are often different from what I do in class. They're provided in case you find them useful.

## Handouts

These are handouts from class. Often they summarize material from the notes.

## Software for Math 311

You'll need some software to plot surfaces for a couple of the problem sets, and you may find it useful in checking your work. While there are many software packages you could use, I'll support two: Mathematica and maxima.

These tutorials give brief instructions and sample commands for doing the homework problems that require maxima or Mathematica.

• Mathematica tutorial - Use this if you're using Mathematica for surface graphing
• maxima tutorial - Use this if you're using maxima for surface graphing
• Vector fields - maxima and Mathematica commands for plotting 2-dimensional vector fields

[Thursday, April 12] The original version of the handout on plotting vector fields had a typo - the Mathematica command used the old version of the function. Newer versions of Mathematica use `VectorPlot` rather than `VectorFieldPlot`. The handout linked above has been corrected to reflect this.

## Problem Sets

Problem Sets are due by the end of class on the days listed below (and on the problem sheets. You don't need to print out the problem sheets (but you may if you wish); you can do the work on the problem sheets or on separate pieces of paper. (Staple everything together, please.) Be sure you've attempted at least the required number of problems to receive credit.

[Wednesday, April 18] There was an error in the problem statement for Problem 2 in Problem Set 40, and also in the corresponding example. As usual, you got credit for the problem if you attempted it. The y-coordinate of the curve was incorrect and and so was the work that followed; with the given y-coordinate, you get an antiderivative that probably can't be done. I've uploaded corrected versions even though that homework has already been turned in, to avoid confusion if you look at the solutions.

## Problem Set Solutions

Solutions to the problem sets will be posted after the problem sets have been collected.

## Review Sheets

Review Sheets are to help you study. They are not sample tests. The presence of a problem on a review sheet does not mean there will be a problem like it on the test. And there may be test problems which are not like review sheet problems.

If you're having personal problems: Please consider seeing Counseling Services. They're on the 3rd floor of Lyle Hall; they're free and confidential, and they've helped many of my students. It's natural to want to fix things yourself, but if your problems are causing you to miss class, to get behind in courses, or to get poor grades, it's best to get help.
