@acer Definitely, I saw that as well. I'm working through a problem set on graphing Polar Equations so there's a lot of converting back & forth between polar and rectangular coordinates depending on how the problem is worded.

Btw, you hooked me on MaplePrimes.com. The same problem set has tested my mastery of the TI-84 Plus & Maple (e.g. this post). I'm glad to be getting a better grasp on both utilities. As I get deeper into mathematics I expect I'll be coming back to this site more than a few times. Thanks again!

@acer Perfect, thank you @acer. I hadn't used the axiscoordinates setting previously so it was defaulting to polar coordinates; I assume that's what I was missing. Very helpful. Thanks again.
