I have just been asked, by member DrNourian, to include this 3D graphing calculator reference

to our "Reference Material" thread which can be found in the __sticky topics on the right of the page.__

This is a direct link to the graphing calcuator. This is a downloadable calc and there is a free version.

I have not looked at it very much but it looks like it might be a very good resource.

Perhaps other people would like to take a look and comment upon it :)

Yep....this looks to be a pretty cool little app.....it will install as an icon but you can drag it to your taskbar .....in my brief experience, the graphing takes a few seconds to generate, but it's worth the wait!!!

Here's a generated pic of a couple of cones....the equation is z^2 = x^2 + y^2

CPhil, thanks for posting that nice image of Graphing Calculator 3D.

Curious, you mentioned that it took a few seconds to plot that graph. But plotting that graph should take less than a second. I wonder if high-precision was enabled by mistake. It should have been off by default as most calculations do not require that kind of precision. You can check that by clicking on View > Precision menu. In there, Math Library should be set to "Double (Fast)". Hope this helps :)
