Whakaoti mō T
\left\{\begin{matrix}T=\frac{d}{r}\text{, }&r\neq 0\\T\in \mathrm{R}\text{, }&d=0\text{ and }r=0\end{matrix}\right.
Whakaoti mō d
d=Tr
Tohaina
Kua tāruatia ki te papatopenga
rT=d
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
\frac{rT}{r}=\frac{d}{r}
Whakawehea ngā taha e rua ki te r.
T=\frac{d}{r}
Mā te whakawehe ki te r ka wetekia te whakareanga ki te r.
