y=xy*sin(xy) simplifies to y=asin(1/x)/x, but this causes a bunch of missing solutions (values in the original that are not in the simplified version). But yeah, it would probably be easier if I learned KhiCAS first.ġ. Your system is more powerful and easier to write scripts for, but Casio's UI is easier for most users to learn. I think KhiCAS vs Casio is like CLI vs GUI. Is there a way to have it automatically re-render my graph if I scroll beyond the minimum and maximum x or zoom in to a level where less than 384 points are in view, or will I just have to find out in advance how much of a graph I need? Is it simply because you only draw when you are done with the math and then don't redo all of it every time I zoom and scroll, or do you have even more optimization? And why would Casio make their built-in graphing so inefficient if there is potential to be much faster?ģ. Your graphing is SO MUCH FASTER than Casio's built in graphing. (I believe that key is wired to a CPU interrupt pin, if it will help in any way) BTW, that graph even overloads Desmos and GeoGebra on my laptop, so I was not expecting it to be fast on my calculator.Ģ. If I launch something that freezes my calculator such as plot(Y,xY*sin(xY),x=-20.20), is there any way to stop it other than the reset button? Casio's apps let me press AC/on to interrupt a computation. I think integration with the system clipboard would be nice because it would allow people to use Casio's easier UI for most things and KhiCAS when they want a little more capability. However, I still honestly find Casio's UI much easier to use. After playing with it for a bit, I realized that it is a lot more than that. Because you said in the main post that it is a CAS system, I for some reason thought it was purely CAS and not much else.
There might also be more differences I haven't noticed, but what are those two different screens meant to be used for? They behave almost identically, except the first one has only black text and the function keys are algb, calc, view, cmds, Aa, and File, and the second has color-coded text and the function keys are tests, loops, misc, cmds, Aa, and File. Pressing "exit" alternates between two seemingly independent screens, one that says "Xcas RAD session" on the top and one that says "Xcas session - 1/1" on the top. I can copy-paste within "Xcas session - 1/1," but it seems to function independently of the rest of the calculator, so I can't copy something in, do some work on it, then copy it back out to use the native functionality again.ģ (not an issue, but I might as well put it here). In "Xcas RAD session," I am completely unable to copy-paste because it seems like the copy button (shift+8) doubles as another paste button or something for some reason. I can't seem to get the calculators clipboard to work in KhiCas. (The fresh copy takes about 5 seconds to close, which is longer than any other app I have but actually reasonable.)Ģ. What could KhiCas have done to make it so hard to clean up? Or did I somehow break it?ĮDIT: I determined that this issue is caused by me having a corrupted binary. I have been told that the delay is because the application is very large, but Physium, which is almost as large, does not experience the issue. Handled by the keyboard handler) but when the user opens the next application. From my understanding of the OS, applications are terminated not when the user switches to the main menu (which seems to be Opening any other application after I use KhiCas takes a really long time.
I have it installed on my CG50, but I am having some issues with it.ġ. * programming with Python-like syntax, including a step by step debugger * exact eigenvector/eigenvalues (vs numeric in Eigenmath) * solve equations, systems, differential equations, recurrences * discrete symbolic sums like sum(k^2,k,1,n) * much more antiderivatives: integrate works with algorithms, not with a table of integrals.
#Eigenmath user guide series#
* asymptotic series expansion (Taylor expansion at infinity) Eigenmath, here is a non exhaustive list: I planed do that in a couple of days, just to make sure there is nothing evident to fix (consider the current version as a release candidate).Īs for what it can do w.r.t. Welcome to Cemetech, parisse, and thank you for sharing this with us! Would you consider uploading KhiCAS to the relevant folder in our Downloads section? I'm also curious what it adds on top of Eigenmath, given how much I've enjoyed gbl08ma's port of Eigenmath to the Casio Prizm.
