i am hoping that somebody can help me with this. i'm trying to figure out how to do a polar plot where my function is defined on a small range (ie 0<theta<pi/2) and then is symmetrically mirrored from 0 to 2*pi. i have attached a picture which is kind of what i am looking to do, but in that case to get each side i had to define different functions, which is not what i want to do. thanks for the help.
