Typed equations are hard to read, so it is worth some extra effort to learn how to include gracious, even beautiful, equations in e-mails.
To do this:
- choose an equation editor. My choice is a Chrome app:
which uses LaTeX to compose equations. Any other editor which shows the equation in traditional form will do.
- Once your equation is ready, activate the Snipping Tool (Windows specific, presumably there's a Macintosh equivalent), and clip the equation off of the screen and hit Ctrl-C, to paste the contents into the clipboard.
- In your e-mail program (I use GMail), insert the clipboard-stored picture into your text, i.e., use Ctrl-V to paste the clipboard contents at the cursor into the text (if this fails, save the equation image to the desk top and then insert the "picture" into your e-mail text at the appropriate place) .
Voila.
