Convolution in GeoGebra linux desktop version

Is it possible to do a convolution, or in general, an integral over one variable of a two-variable function in the linux desktop version of geogebra?

This version does, for some reason, not allow one to do a definite integral, while specifying the variable to integrate over...

Please say what you tried exactly that didn't work (ie what did you type?)

First, I define a function, say


f(x)=cos(x)

Then I try to perform a convolution:


g(x)=Integral(f(t)*f(x-t),t,0,1)
The response I get from GeoGebra is "Invalid input: Undefined variable: t"


If I leave out the ", t" part (second argument), the response is the same.

Is there a CAS window in the linux desktop version? If so, how can I access it?

view CAS

I am afraid that the problem persist you can get integral(cos(x) cos(t-x),t) then sustitute t by 1 and 0 and -

Select View in the menu bar to open the submenu with all the available Views in v.5

Click the hamburger icon (top right, three stacked lines), then select View to open the same submenu in v.6

Ah, I just installed the debian (apt) package, which appears to contain version 4. That explains a lot. Thanks!
