Le forum de XCAS

Well, this is cool! I'm installing the compiled version right now, and installed the web version with local files. It looks amazing and works great. I noticed the instructions for using Xcas on a smartphone suggest opening the web version hosted at www-fourier.ujf-grenoble.fr. (It also mentions Xcas...

For what it's worth, here is a small patch to update the documentation cascmd_en.tex.
(It's a text file, but I had to add the pdf extension to upload it.)

Oh! Neither the English nor the French manual mentions using "quote" as a third argument; that should probably be fixed. Also, "help(subst)" actually gives an example where both the second and third arguments are equations. As compsystems points out, that would violate the 0,1,infinity rule. But I s...

The documentation says that the subst command takes two or three arguments. The third argument is intended to hold a value (or list of values). I would guess that through a quirk of programming the third argument can be used for another equation, but this wasn't intended. Since subst can't take more...

This isn't really a bug, but I wasn't sure where to put it and thought it might be worth mentioning. I was just compiling giac on a new computer with Debian 12. When I first tried to create a deb file with mkdebian, I got the error, with both the latest stable and latest unstable versions, dh_clean:...

Also, it doesn't integrate dy/dt back to y if it is entered as
diff(y(t),t).
If you enter
eq1 := diff(y(t),t,1)
then again
int(eq1,t)
returns undef.
Oddly, perhaps,
diff(y(t),t,1)
returns
diff(y(t),t,1)
I expected
diff(y(t),t)

Another question: I want to know if the square root (or, if possible, any n'th root) of a large integer is an integer, how do I do this? (in other words, I'm not interested in the root itself, only in knowing whether it's integer.) I'm sure there's a good reason this isn't a good solution, but the ...

That's exciting!
Does the 2.0 release have any meaning other than a number bump?
Regardless, it's cool and looks good!

The IT department will install what I need, but it won't be installed until next school year. Which will be fine. Thanks!

I think the LaTeX->PDF->Print would work for me, but I'm not sure about my students.

Xcas is installed on my university's computers (they use a Windows Thin Client), and printing from there cuts off part of the session. For example, I've attached the print result of a small session (winsession.ps). I use Ubuntu, not Windows, so I tried it on my computer. This time, the session was t...

The magnets probably have a white background because I use the "switch to whiteboard" option; it somehow changed to white on black when I pushed the "Forum" button. This blackboard covered something I wanted to show my advanced calculus class, I thought it'd be fun to try it on tableaunoirxcas. It w...

I can get tableaunoirxcas to work, but it looks as if the Xcas magnets get messed up when I post the url. I'll figure it out.... https://www-fourier.univ-grenoble-alpes.fr/%7eparisse/tableauen.html#python=0&radian=1&width=12600&height=800&00840004npsr&000d00S2GwJpKqMoLnMq&000g00Q2IvKpLpJpLqKpMoLoMn&...

(I'm not sure if this is the right subforum to post this, but here goes...) In the index_en.html file that comes with Tableaunoirxcas, the code that actually saves the session (in the "My Board" part of the menu) is missing. It is there in index.html, so I can get it working with a cut-and-paste, b...

Never mind, I guess, Everything works fine without the eval(...,0) there (and I'm a bit surprised it worked in that one case with the eval).
