Talk:SigmaYY Command
From GeoGebra Manual
Sigmayy[list of points]
The quick reference in v.4 shows there's also a sigmayy[list of points] available option. This manual page doesn't show it. I tried to use it in ggb v.3.9.164.0.m and returns undefined for a simple list of numbers like {1,3,4,5,6} By the way, ggb doesn't tell me that the syntax is wrong and other entries are expected e.g. points. Is sigmayy[list of points] unused in v.4? For the moment i leave this page into Outdated. --Mathmum 10:08, 14 February 2011 (UTC)
