parametric plots

[edr58 (eli rex)]

Whenever i try to plot a circle using the confines of {t,0,2pi} the system says that the term 2pi is not a machine-sized real number. I guess I’m wondering How do I use pi

Buillt-in functions and constants are always capitalized. Additionally there must be a space in between numbers. So instead of using “2pi”, please use “2 Pi”.
