Hello, Pacific Tech 2D Grapher is now on the Mac App Store for 99¢: http://itunes.apple.com/us/app/2d-grapher/id451771111?ls=1&mt=12 Also on the Mac OS X App...
Thanks Ron, great to have these tools to offer when people have need for them! Attached is a small inequality plot for 2D Grapher. -Pete ... -- Petri Sirkkala,...
Not to up on the theory of iterated functions, and the color scheme may be a bit misleading, since it's symmetrical with respect to the complex argument, but...
Thanks a lot, Art. Hopefully soon, we'll be able to look at the connection between iterated functions and the Julia and Mandelbrot sets. It may be too much of...
... Option-< and Option-> will do it. Actually, you don't hold down the shift key, so strictly speaking it's Option-, and Option-. I.e., while holding down the...
Ron- I'm not sure about the relationship between these pieces of software and Graphing Calculator. They look like they are pieces of the full application...
Hello, My first foray playing with the notion of online math books is free at http://itunes.apple.com/us/app/conic-sections/id458033479?ls=1&mt=12 to join...
A short tutorial on direction fields for ODEs with GC4. I found this in the help under Graphing equations, Two dimensions: Here's an elaborate example where I...
Had to use a workaround to have indexed derivatives. Interesting that the odd degree determines overlap the even degree terms at the extrema and the inflection...
We can pass any number of terms to this version. We can see the large oscillations at the edges here, which limit the practical uses of this form of...
Quasi-Spherical Orbits, or QSOs, are the space curves traced by a point rotating simultaneously around two or more axes. They model a number of dynamic...
Hi, math fans, I spent a long time getting the nitty-gritty down in a simple case for how the interpolating polynomial through 2 points converges to the...
http://intumath.org/Math/Algebra/Finite%20differences/interpolationand.html has my latest efforts with GC on interpolation. Important for relating difference...
I'm very interested in these curves. I don't think anyone has really confronted the mystery of atomic orbitals on a basic level. I don't think it solves the...
Hello, 4D Grapher draws two dimensional pictures of the three dimensional shadows cast by four dimensional geometry. Graph and animate curves, surfaces, and...
... Looks great! I just used "a" as the slider variable to be able to animate it. And I made tubes out of the edges. ... As I said, amazing work! These are...
Have installed it on my dashboard, thanks! I guess the formula means that what we're looking at in the right pane is the inverse function, exp( ) something. ...
... If you hide the axes, you'll just see the custom made ones: Here's a file that can be used as a template for any time you want the x-axis to be labeled in...
