Polar and Cartesian on the Same Graph? HP Prime
Hi, is there a way to graph polar and cartesian on the same graph on the HP Prime? In other words, can I graph r(theta) = r*sin(theta) and x^2+y^2=1 on the same plot?
Thanks.

A less mathematical alternative could put the two graphs on the same screen rather than on the same graph.
I was thinking: Draw a graph Save a bitmap Draw 2nd graph Load image of 1st graph with some transparency. Which has the advantage that you don't need to rewrite every equation you may want to share a graph with. But it's not exactly on the same graph.

Thanks guys, I'll keep that in mind. These ways are a good work around to check if my Cartesian to Polar conversions are correct.

Doesn't the Geometry app have this functionality? I've haven't used it much but I know there's the option for all the different types of graphing.

Ah yes the Geometry app! This is what I was looking for! You can use plotpolar() and plotimplicit() to graph your polar and cartesian functions respectively. Thank you TheLastMilennial! I watched your indepth review on the Prime G2 not to long ago and it was great!
