Graphing Calculator 3D

Far more powerful and useful than other graphing applications without the complexity or tedium of a full-on mathematical suite. You can define parameters/variables and their ranges and see how your system behaves with different parameter values. It's pretty much as easy as typing in the formulas and see it render. The software also generates tables of values for the function. However, the interface is unintuitive and has limitations and glitches that make the experience frustrating. Why can't I use R as a variable? Why is it that when I've clearly declared a variable, the formula that uses it says I haven't? Why is it so tedious to change graph parameters? It would also be helpful to be able to annotate elements of the graph to keep track of their interpretations and also for key points such as inflection points.. There also doesn't appear to be any way to automatically discover inflection points and intercepts. This along with annotation would be a big help.

I like it all. I wish there was a way to create volumes of revolutions

it is so fun to mess around on It even helped me with my math work
