Thanks to the overwhelming positive response to my release of the g(Math) Add-on. I have received lots of great feedback and I have updated the Add-on to include a lot more Prebuilt LaTeX expressions.
You do not need to do anything to get the newest version of the Add-on if you already have installed it (which is a huge benefit that I see about Add-ons)
If you have other expressions you would like to see added, let me know!
I am in the process of adding the functionality to graph more than one equation on the same same graph and it should be updated by the end on the weekend.
Additionally, g(Math) for Sheets should be live in the next week which will allow you to create Form questions using g(Math)!!
