how I can add a polar function to one part of a larger design? Or
It sounds like perhaps you are trying to use a circle for a path to define the polar pattern, if so that is wrong, you define the axis.
Honestly this is well explained in the wiki, search for partdesign workbench, then find the pattern features and read their pages, if still confused then come back here.
Also note that with partdesign pattern tools you can only make patterns on a single solid and not an array of separate solids. For Arrays see Draftwb Array.
