Commands Unknown

Not a Problem

I don't know if I'm doing it wrong, but there are many commands which are "unknown" even though they are detected (it shows the syntax) as I type them. The commands I tried were Limit, Derivative and Integral. I don't know about other commands, but these don't work. By the way, I'm using the web version in chrome.

Do you mean this version? https://www.geogebra.org/classic


Does it work in Chrome?

That version doesn't autocomplete Limit, Derivative for me

If I type "lim" and continue typing '(' it will turn to Capture.png; at this point, there was already a warning at the left, I thought it was because I haven't filled in the inputs, but if I hover over the warning sign, it says Unknown function: Limit. If I then click out of the box, it will consider 'lim' as a variable and set the value to 1.

If I fill in the values at Capture.png so it becomes Capture 2.png; and then click out of the box and click the box again, as if to edit the equations, it becomes Capture3.png.

However, if after I fill in the values so that it becomes Capture 2.png, and delete the values, so that it looks like Capture.png again, and then click out of the box and click the box again, it won't consider "lim" as a variable as before, but it will become "Limit((), (), ())"

And in all cases, it doesn't recognize the command. I haven't tried to see its behavior with the "Derivative" command, but I know it just doesn't work. By the way, the only command from the three I mentioned, which is listed in the commands list when the ellipsis on the top right corner of the virtual keyboard is clicked, is the "Integral" command, the "Derivative" and "Limit" commands aren't even there. However, if I click the d/dx or the ∫ on the keyboard, it will insert "Derivative()" or "Integral()" on the box I'm typing in, even though the "Derivative" command isn't on the list.

to have exam mode implies to have not derivative, undefined integral nor limit

strangely I do not find exam mode here

Graphing app has the CAS commands disabled, so it can be used for exams (Exam mode is available only on the mobile apps).

If you need the full power of GeoGebra, please use the Classic version.

Same problem here with the mobile app.
