Rectangular ne polar

Akatonnyeze kasobola okunnyonnyolwa mu ngeri bbiri. Mu rectangular coordinates, $P(x,\ y)$: $\displaystyle x$ mu bukiika ne $\displaystyle y$ waggulu. Mu polar coordinates, $P(r,\ \theta)$: obuwanvu $\displaystyle r$ okuva ku ntandikwa n'ensonda $\displaystyle \theta$. Okuva ku rectangular okudda ku polar, $r=\sqrt{x^{2}+y^{2}}$, ate $\displaystyle \theta = \tan^{-1}(y/x)$. Okuddayo, $x=r\cos\theta$, ate $\displaystyle y = r\sin\theta$. Kalakuleta ekola enkyusa zombi, era etereka n'ebyokuddamu: $\displaystyle r$ oba $\displaystyle x$ mu tterekero X, ne $\displaystyle \theta$ oba $\displaystyle y$ mu tterekero Y.
