hi,
I just wanted to know how do you basically try and graph a curve like this r(p)=(2p-p^3,2p^2)?

or if not, just a simple r(t)=(tcos(t),tsin(t),t) with t>0? what do you start off with and is there any transformation you can make to this formula to make it more obvious what kind of shape it will take?

Thanks
