Mathematics for Computer Science — Lehman, Leighton, Meyer
Reading this textbook is not required, though many students in the past have found it helpful in reinforcing
what's covered in lecture!

For many of you, this is your first time writing proofs, and even for those who have written proofs before,
what we consider a good proof in CS22 likely differs from what made a good proof wherever you were writing them
before! Check out the proof virtues document below to acquaint yourself with what we consider a good proof in
CS22. ** Your proofs will be graded with respect to this document **, so be sure to read it carefully, and
come to hours with any questions.

# LaTeX Resources

LaTeX (pronounced *la-tek*) is a program that you will be using to make your homework solutions look
beautiful. The sample proofs above were written in LaTeX to give you an idea of what documents written in
LaTeX look like. LaTeX allows you to incorporate mathematical notation into your proofs, and because this
class involves a healthy dose of mathematical notation, LaTeX is going to be very useful! Using LaTeX is
required after the 2nd homework.

We don't expect you've ever done this whole LaTeX business before, and that's why we're giving you some time
to learn it! To get started, we recommend creating an account on Overleaf, an online program for writing and compiling LaTeX. After you
do that, here are some links to check out:

Honestly, please use
Overleaf. It's so
much easier than installing anything on your computer. Trust me.

In general, a really good resource for learning LaTeX is the web. When you have a question, google it, and
you'll likely find someone who had the very same question!

Below is a template you can use as a starting point for your homeworks.

LaTex Homework Template

If you'd like to download LaTeX on your computer, here are some resources to do that:

If you're using LaTeX and you just don't know what the code for some symbol is, here is a helpful list to
start:

Common LaTeX symbols

Alternatively, this is a neat site which will return the LaTeX code based on handwritten input (although
searching your question on the web is likely more efficient):
