Hey guys. For my honors precal class, we just started learning about graphing polars and all that nonsense and we have a project due thursday where we have to make up out own polar formula and then draw the graph. I really want to do something cool but I can't think of anything. Please help!

Your question is pretty vague. If all you have to do is pick something to graph, just do r = cos(theta)

"Cool" is in the eye of the beholder. What about

r = cos(2θ)+cos(4θ)

@LCKurtz, thank you very much. I sat for like 30mins doing random formulas and half the time I'd just get circles and others just a bunch of scattered lines and stuff. but thanks, thats the one I'll use

You're welcome. If you change the cos(4θ) so sin(4θ) you get a nice looking dragonfly.

Though it's too late, that looks cool to me.
