Homework

HW00 (Optional, not graded)

Here are my solutions for HW00, along with the .tex file, for your reference. In the future, I'll just post a PDF of abridged solutions. [HW00solns.pdf] [HW00solns.tex]

This is not graded, though I encourage you to make sure you can do it. The purpose of this homework is just to get you set up to TeX your future homework solutions, and to make sure you can upload your homeworks to Gradescope.

Here is the TeX file for HW00: [HW00.tex]
Here is a PDF of the homework, provided for your convenience (there is no reason to print this out): [HW00.pdf]

You'll find a version of the following instructions at the top of the HW00 PDF:

Instructions. Create a free Overleaf account, and create a new project (e.g. "MAT150A-hw"). Upload the provided "HW00.tex" file for HW00, and click on it on the sidebar. Then, press the big green "compile" or "recompile" button at the top of the right half of your screen. You should then see the HW01 PDF show up on the right half of your screen.
There are two exercises in this HW. Type your solutions directly into the code, compiling every once in a while to admire your work. When you are done, press the download icon next to the recompile button to download your solutions as a PDF. Submit this PDF to Gradescope.

Reminder. Your homework submission must be typed up in full sentences, with proper mathematical formatting. The following resources may be useful as you learn to use TeX and Overleaf:

This lecture will also be on the board. From the survey (Lecture 20 participation slips), a majority prefer more board-based lectures. In the future, I will continue to incorporate slides when necessary, but default to boardwork.

We will complete our discussion of the Crystallographic Restriction and then talk about HW06.
