Ok, I know the basic steps of finding the slope of polar curves. You just put in the equation and select "calculate" and then you have 3 options - value, dy/dx, and dr/dtheta. But I'm really confused about something. I thought dy/dx was the standard slope/derivation expression for polar curves because I've been doing polar/slope problems using dy/dx. What's up? Also, just how exactly do you find the slope of polar curves? I've been trying to use the calculator to find polar slopes but my answers NEVER match the book and they're not even remotely close most of the times.

Help please!
