How to get equations and symbols into your Word document
1. Microsoft Word has good ability to write simple equations. There are three keys to doing this:
a. Insert > Symbol gives a number of useful symbols. Note that this works in WebTycho TFE also.
b. Format > Font allows you to produce subscripts and superscripts. This works in WebTycho TFE also.
c. Equation Editor is a powerful standard part of word. Do Help "Equation Editor". If you can't find it, you need to install it from your original Word disk.
2. For a more powerful ability, use MathType. This commercial product works seamlessly with Word. There's a free 30 day trial. Purchase at academic discount is $57. That may or may not be an investment you would like to make. If you or anyone who shares your computer (you know, my kid lets me use it for an hour every day), plans to take another mathematics or statistics course, it may well be worth the investment.
3. What do I use? I don't use Word at all for documents that are heavy in equations. I use the the standard tool that mathematicians prefer. That's TeX. It's freeware produced under USG contracts. To find it, type "Free TeX" into your browser. My preference is a commercial version called PCTeX. It costs money and requires a bit of programming skill. The results, though, are worth it. In better versions there's an integrated ability to produce output as an Acrobat file.
