Length Command is not working in Graphing calculator

Please read the alert when opening the Graphing Calculator! If you want to use these and other geometrical tools and commands please use GG Classic or the Geometric Calculator. In both of them you will find the geometrical tools and commands.

there is not any ALERT when you open graphing calculator online with the link

I think some commands(object) must be present for some objects ie: YES for length(list) NOT for length(curve)

about pop-up alert: just a minute before my answer on this post I answered another one complaining on the appearance of such an alert ( link https://www.geogebra.org/gr...).but I haven't got an overviw when eventually there isn't. And in general, of course one can discuss about choices what to remove or not... And indeed if one cannot construct segments anymore but still lenghts then the Lenght command wouldn't be a problem. But perhaps the initial question was mentioned for graphic objects.

Try the GeoGebra Geometry app

The pop up actually says, "We have removed geometric construction features."

Length is not a geometric construction feature. I was not aware that all commands under the category of Geometry Commands are not available in graphing. You may want to update that information on https://wiki.geogebra.org/e...

I normally use the command in the context of Length({4,5,6})=3, which is not geometric.

Almost every graphing calculator I have used has a sample size function. On ti-84 it is also under 1-Var Stats as n=

Could you create another command? Size(<list>) = number of distinct elements in <list>.

Seems a little silly to have a frequencytable(true,<list>) and read the total size in the last row but not have this easily found directly.

I get a command stating that Length command doesn't exist.

I try to measure the length of a vector.

When I try to calculate the length using he formula:

L = (x(V)^2+y(V)^2)^0.5 then it keeps stating L = X(V)^2.

Please try the new version (v587)
