Recursive functions and Advanced Graphing

[danielmewes]

The Advanced Graphing app is rather special in terms of which functions/equations it works for. I don't know what exactly the requirements are unfortunately, but I'm getting the same error for `RE((x+i*y)^3)=0` for example (the i appears to be the problem). I suspect that recursive functions might simply not be supported there.

I think there's some sophisticated algorithm at work in the Advanced Graphing app that performs some kind of analysis and/or calculus on the equation, though again I'm not sure what exactly that is. Maybe it's using gradients to find roots or something like that?
