you don't need polar coordinates ... if is such that then where
because you can just put then since as we'll have that
But isn't that exactly what I did, I let regardless if it was polar coordinates, and then as we have that , so whether or not I called it polar coordiates wasn't it basically teh same concept?

you actually did use polar coordinates! haha ... anyway, my point was that it's true in general for any function
