Rectangulaires mpe polaires

Point ekoki kolimbolama na ndenge mibale. Na coordonnées rectangulaires, $P(x,\ y)$: $\displaystyle x$ na mopanzi mpe $\displaystyle y$ na likolo. Na coordonnées polaires, $P(r,\ \theta)$: distance $\displaystyle r$ banda na origine mpe angle $\displaystyle \theta$. Mpo na kolongwa na rectangulaires kokende na polaires, $r=\sqrt{x^{2}+y^{2}}$, mpe $\displaystyle \theta$ ezali $\displaystyle \tan^{-1}\frac{y}{x}$. Mpo na kozonga, $x=r\cos\theta$, mpe $\displaystyle y$ ekokani na $\displaystyle r\sin\theta$. Calculatrice esalaka kobongola nyonso mibale, mpe ebombaka biyano: $\displaystyle r$ to $\displaystyle x$ na mémoire X, mpe $\displaystyle \theta$ to $\displaystyle y$ na mémoire Y.
