... I agree completely with anyone who says to base all math on "Discrete Math" -- understanding the basic underlying logic (sets, relations, etc.) as deeply...
(Note: all the grid lines below are at distances of 0.25 times the length of the respective unit-vector.) It doesn't look like the transformed unit-vectors are...
Here is a way to trace out the u, v values of a parameterized surface. Could by used with 3D arrows to vector-add corresponding u, v, points on multiple...
I've been writing some files to illustrate miscellaneous special functions [mainly orthogonal polynomials of various types].* They're usually indexed by one...
Anyone have a copy of Abramowitz & Stegun ["Handbook of Mathematical Functions"]? I'm looking at entry 8.7.1 as a way to generate higher order spherical...
... I'm not sure if I'm using exactly the Legendre functions you want. If not, if you post them, I'll try again. In the first attempt I made, there seems to be...
... Well, it looks like basic recursion works in GC!! Here's a recursive definition of the factorial function: Can't do it with derivatives though. None of the...
It looks like this kind of recursive definition is too complicated, unfortunately: For some reason, this is getting mis-parsed: But even if I fix this, it...
Hello, Graphing Calculator was not designed to handle recursive functions. This is on the list of features under consideration for a future release. The...
Well, for the time being I've taken a brute force approach and entered the function definitions of the associated Legendre functions through order 8 by hand....
... From the online version of A & S at http://www.math.sfu.ca/~cbm/aands/page_335.htm: 8.7.3 (below): I found this in the "Index of Notations" section at ...
I'm trying to define the Gamma function, following Mathworld's entry at ... Unfortunately, I can't seem to get GC to accept any of these. At any rate, the...
http://mathworld.wolfram.com/GammaFunction.html has a lot of special cases for computing the Gamma function. I haven't checked it out in detail, but you might...
Sorry, I wasn't using a legitimate graphing method for complex functions in my previous e-mail. But the following doesn't work either. Don't mean to be a...
It would really be nice to be able to have custom colors in the 2D background, e.g., to give the impression of light rays. This would make for a very intuitive...

Thanks for catching Pochhammer's symbol! I'd even looked over the gamma function section -- twice, not less -- and not spotted that. Moreover, I've...
Can Graphing Calculator be used to make a web-based document with sliders? For example, can I create a document that I can post on the web that will allow...

... Not exactly, as far as I know. But there are two related options. You can save a file as a web page (File -> Save As...), but of course it has no...
Correction- ... I just checked my notes. I believe the latest Windows version of GC *DOES* support sliders. I don't know if the viewer does, though, as I ...
These look very good. Would be good to have them in the Physics section, if you feel like uploading them. I'm wondering what, if anything, these plots might...
... Thanks. Yes, I intend to. Actually, I have a bunch of files to upload to the physics section when I've cleaned up some things and can take the time. The...
