It does not appear that you can enter the binomial coefficient or the choose-function of combinatorics. I'm trying to use the parenthesis in the third drop-down menu in the equation editor, but they add standard parenthesis. I want my end result to look like this: binomial coefficient

Can this be done or must I use a different notation?

What is the difference between standard and the one/s shown in wikipedia ? Could you re-edit the question to show exactly (the equations in wikipedia are png's so you can place them in your post) which notation you are looking for because I just did it in Google Docs and saw no problems. –  phwd Jul 18 '10 at 19:14
    
In general if you run into troubles with the equation editor in Google Docs try searching on how to do stuff in LaTeX.. Just keep in mind that google doesn't support all the LaTeX commands for the equations.. –  Lipis Jul 18 '10 at 19:28
    
Lipis: The new Google formula editor doesn't support ANY LaTeX that I can see, and the documentation backs that up: docs.google.com/support/bin/answer.py?hl=en&answer=160749 –  Thomas Owens Jul 18 '10 at 22:44
    
@phwd: The standard one is the first one shown in Wikipedia: upload.wikimedia.org/math/3/8/2/…. Also, I'm not trying to place it anywhere in a Google Doc, but as part of a much larger equation. –  Thomas Owens Jul 18 '10 at 22:45
    
if you open the equations editor and click around to have some symbols vsible and you open the preview image in another browser-tab (or check the url of that symbol), you see that it uses google-chart api and its tex backend. it does not support all latex-things but it is for sure pretty much tex involved in that piece of software. –  akira Jul 19 '10 at 8:17

It is true that the notation for the binomial coefficient isn't included in the menu, but you can still use it by using the automatic shortcuts.

When in the equation editor, type \choose

Type \choose

then press space

That's it!

type \choose and press space bar

Could you elaborate on this? –  Vidar S. Ramdal Apr 2 at 8:08
    
This is the same answer that Matias Rasmussen gave. Just do this, and you will see what happens. –  rakensi Aug 7 at 15:53

Google Docs seems to use the Google Chart API (or better the tex backend of the chart API) to display equations.

So, as long as

http://chart.apis.google.com/chart?cht=tx&chl=%5Cbinom%7Bx%7D%7By%7D

(which is url-encoded for \binom{x}{y} at the end) results in

you will have problems to enter that formula.
