Homework will be due roughly every other Friday, according to the schedule below. Each homework will consist of several problems, but students are only required to submit solutions to one problem.

Writing Mathematics

In mathematical and scientific writings, equations should occur naturally within full sentences and flow with the surrounding text. The goal is to communicate your mathematical reasoning to another person, and this usually requires more than just a string of equations. It is strongly recommended that students practice this style of writing in their homework. The homework solutions posted on this website can be used as examples, and a some good resources are


A great way to write mathematics electronically is to use LaTeX. LaTeX is widely used for the publication of scientific documents in many fields, including mathematics, physics, computer science and engineering. Some good resources for getting started with LaTeX are

The homework assignments, solutions, midterms, and finals for this course are all written in LaTeX, and I will post the LaTeX files for all homework assignments throughout the term.

For preparing LaTeX documents, I use the command line editor vim, along with vim-LaTeX, and a PDF-viewer that automatically updates when the pdf file changes (e.g., Skim on Mac, or Evince in Linux). I have used this setup on both Mac OSX and Linux operating systems. Beware that while vim is a powerful text editor, it has a very steep learning curve.
