Has anyone tried to graph the classic surface of Revolution problems from Calculus using GC? It seems like one should be able to see the region in the x-y...
... I'm not sure exactly what the equation your graphing here is. I got a general formula for parameterized curves out of the book "Modern Differential...
... Maybe the following is more what you wanted. It shows a revolving "slice" going around inside the surface of revolution. Also uploaded to Files > Calculus,...

Chris- You do fine work, sir. Those files you posted recently illustrating surfaces of revolution do a wonderful job of showing off Graphing Calculator....
My latest efforts to understand parameterized 3D surfaces. Trying to keep it simple, just rotates a parabola around to form a surface of revolution and uses...
I fixed a problem witht the latitudes not getting reset properly when the function definition was changed. You still have to figure out the inverse function to...
Fixed the previous file so range setting of x works right. Now you can have a hollow core in the middle as the whole thing is traced out by the profile region....
Here's a 3D tetrahedron in a cube, for Graphing Calculator 3.5. Shows how with some work GC can be an amazing tool for teaching solid geometry. I'm trying to...
A tetrahedron centered on origin, faces and edges colored to show its structure. Rotatable and translatable via sliders. Trying to figure out how to put cube...
Ron, Don't know if I've said so yet, but GC for OS X is an absolutely amazing piece of work! Thank you again and congratulations. I notice I can usually use...
I have volunteered in the middle school for several years and see GC as a way to interest and excite many students. In so keeping I have been working on a...

I'll second Chris' comments. A local IT person asked me why I wanted GC in one of my classrooms -- which they haven't gotten around to yet, but never mind --...
Arne, ... First, go to our web site at http://groups.yahoo.com/group/GraphingCalcUsers/?yguid=54088085 On the left you'll see the "Files" link. Click on this. ...
Arne, Re the tip on uploading files, you're welcome. I liked your file with the cone emptying into the bin. A good realistic way to introduce volume concepts. ...
... Well, if you check the times I posted my files, you'll see that's where a lot of my nights for the past 10 years or so have gone. Maybe GC should have a...
Ron and GCers: I'm still having trouble getting a shadow of the moving patch, as it "morphs" from inital position to final position. I can project a patch ...
Ron, I wonder whether it might be easier to not have the sliders automatically start graphing when you move them. If you've got a lot of sliders you want to...
... This is a bug which occurs because GC fails to fully expand the definitions of functions before multiplying out the matrices. You can work around it...
With a little work, which I'll try to do later, such as putting a picture and/or grid on the patch, it should be a pretty vivid way of illustrating different...
Hello Chris An interesting visualization of these three pyramids inside the cube is to illuminate the three opposite faces of a corner with light of different...
I am a new GC user and I am wondering if it is possible to make slides of 3D surfaces at diferent angles other than the orthogonal ones!(i.e. y=constant or...
Ron, I'm wondering what I'm doing wrong here. I can't seem to use a function definition and graph it in cylindrical coordinates, as shown in the attached...
