From: Michael Kuyumcu on 31 Aug 2006 15:28 Hi, I am very grateful to your effort and help! It works! The code, as you gave, without any alterations, produces the fibonacci numbers! Now I think you can claim to have been one of the first non-tester people who ever programmed the TI-nspire! :-) Kind regards, Michael Kuyumcu Yao Konan wrote: > Well i have done a slight error in my previous post, so the good > version: > > Define Fib(n)=Func: > Local i,k1,k2,r > if n<1: > return "Unknown value": > 0->k1:1->k2: > For i,1,n: > k2->r: > k1+k2->k2:r->k1: > EndFor: > Return k2: > EndFunc > Michael Kuyumcu a écrit : > > > Hi, > > > > on the programmability: it seems that you can use the provided > > programming constructs in *functions only*.

From: Michael Kuyumcu on 31 Aug 2006 15:35 The on-calc system info says otherwise: it treats the whole memory as one block. The system software takes up about 8 or so MB, and the rest is free for you, the user. At least the system info does not differentiate any ram or rom areas visibly. Interesting: fib(10000) produces an overflow, even in Exact mode, while the CAS seems to be capable of handling multiple-precision numbers otherwise with no problems.fib(1000) works, and does so within 2 seconds.

From: Michael Kuyumcu on 31 Aug 2006 15:41 Is there a quick way to test 3D functions plotting capabilities. I mean, now that we know that programming constructs work in functions, maybe you could come up with 4 or 5 lines of test codes for 3D plotting? Of course, I don't know whether that kind of programming would be so easy, but if it is, maybe you would like to try it? Anyway, thanks for considering it!

From: Michael Kuyumcu on 31 Aug 2006 16:06 I agree. I prefer to be able to choose between functions and programs. Anyhow, it may be that I am still missing something basic (while different from the 92 or Voyage) when trying to write a real program. Still, the on-calc reference lists only functions, not a single command like PLOT or anything the like. I just gave the geometry section another look. It seems I can define only functions with one independent variable, not two. I saw an example in the pdf handbook you referenced but I can't reproduce it on the nspire. So maybe it really is bound to 2D? Hard to imagine... Your questions: There is no 8-character limit on variables name. The CAS recognizes and distinguishes between, for instance, the variables ABCDEFGHIJKLMN and ABCDEFGHIJKLN. A problem is not a folder or special structure. It is a plain .tns document. You can arrange any documents in any folders. You can save and save as... documents. BUT: it seems that only the root level of the directory structure can hold folders. When you save as... a document, you are asked into which folder you want to save the document. At that moment, there is no way to see inside that folder. You can only highlight its name, provide a name for the document, and save it into the selected folder. There is a file browser, though, with which you can create folders (only on root level, it seems), view the contents of folders, move files from one folder into another, delete files, erase folders (including their contents!), cut/copy/paste files and folders (folders only on the root level). It is a mono-level tree structure, I'd rather call it a bush structure.

On the TI92 to plot 3D graph you need to put the calculator in 3D mode. Is there a some kind of settings screen ?
