Trying to do a problem I run into about 10 different r's I have to keep track of.

Capital R

Lower case r

Lower case r prime

The r in spherical coordinates

The "squiggle" r (As this professor calls it. Never heard that before this class, but he talked about it like everyone knows. It's just a cursive r from what I can tell.)

"Squiggle" r hat

Normal r hat prime

"Squiggle" r with an arrow over it.

The normal r with an arrow over it

Normal r with an arrow over it prime

So when I see an equation with 3 or 4 different r's in it, my head just explodes. Why is it like this? And am I the only one who thinks this makes it confusing?
