Nyiga on C, Eppeesa lya negative, 3, Eppeesa lya koma, Eppeesa lya negative nate, era wandiika 2.5. Olwo second F ne okudda mu r theta. Olutimbe lulaga r: 3.905124838 θ: −140.1944289 diguli. recall, X ewa r\displaystyle r: 3.905124838. Era recall, Y ewa θ\displaystyle \theta: −140.1944289. Ensonda eno ya minus: epimibwa mu ngeri y'essaawa okuva ku x\displaystyle x axis eya plus, era kalakuleta egikuuma wakati wa −180\displaystyle -180 ne 180\displaystyle 180 diguli.
