The PolarPlot command is located in the Standard AddOn package Graphcs`Graphics`
You need to either load this specific package (<<Graphics`Graphics`) or the package
definition (<<Graphics`)
Notice: ` is the character located on the same key as ~
This is not the same as ' which is the single quote mark.
<<Graphics`Graphics`
F[a_] := Cos[\[Pi]/2Cos[a]] - Cos[\[Pi]/2]/Sin[a];
PolarPlot[F[a], {a, 0, 2\[Pi]}]
