LaTeX is widely used to typeset mathematics and any science that uses a lot of equations and/or symbols. There are many different products that allow one to do this; some are free, others are not. A Mac user can obtain TeXShop for free. Windows users can obtain MiKTeX for free.
Another way, which is probably the easiest way to start out, is to use Overleaf (formerly WriteLaTeX) and use LaTeX through a browser. Upside to Overleaf is that you can easily collaborate on documents (if appropriate, of course) AND there's nothing to install. Downside is you have to be online to use it.
Some links to get you started:
Here are some informational links to Overleaf and LaTeX:
TO TURN IN HOMEWORK IN LATEX (using Overleaf): click on the "Share" button at the top of your "project". Copy the "Read & Edit" link and email it to me. This way you do not need to download the PDF and print it and turn it it. You are more than welcome to print it and turn in the paper, but there's no need. If youturn in part on paper and some is on Overleaf, indicate so on the paper AND within the typed up text. Thus if anyone (namely, you or me) is looking at either one, we know to also look elsewhere for the complete homework set.
