Plotting Strangeness?
I was playing around plotting equations in the advanced graphing app to get fun shapes.
These two equations, and variants, produce some weird behavior when plotting, it's like the calculator (and emulator, though faster) are plotting a bunch of extra points then eliminating them to get the correct line in parts of the plot. X=Y^3 5*Y^2 + 15 X=Y^4 5*Y^2 + 15 (looks like a sigma) Really slows down the plot. Any ideas what is going on? I have not noticed this yet when plotting functions and other non functions like X^2+y^2 are fine.

That's just how the advanced grapher works  by design. It uses adaptive techniques to refine the graph until further refinements are no longer visible within the current window settings.

RE: Plotting Strangeness?
I figured it might be, looks strange the first time you run across it though especially with simple equations like I'm playing with. Thanks.
