Nyiga ne ofune koma, olwo ne 2.5. Nyiga ne . $\displaystyle r$ eri r=3.905124838, ate $\displaystyle \theta$ eri diguli θ=−140.1944289. Ensonda ya minus kubanga epimibwa mu ludda lw'empiso z'essaawa: $\displaystyle \theta$ bulijjo eweebwa wakati wa $\displaystyle -180^{\circ}$ ne $\displaystyle 180^{\circ}$.
