Whakaoti mō a
\left\{\begin{matrix}a=\frac{F}{ℓ}\text{, }&F\neq 0\text{ and }ℓ\neq 0\\a\neq 0\text{, }&ℓ=0\text{ and }F=0\end{matrix}\right.
Whakaoti mō F
F=aℓ
a\neq 0
Tohaina
Kua tāruatia ki te papatopenga
F=ℓa
Tē taea kia ōrite te tāupe a ki 0 nā te kore tautuhi i te whakawehenga mā te kore. Whakareatia ngā taha e rua o te whārite ki te a.
ℓa=F
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
\frac{ℓa}{ℓ}=\frac{F}{ℓ}
Whakawehea ngā taha e rua ki te ℓ.
a=\frac{F}{ℓ}
Mā te whakawehe ki te ℓ ka wetekia te whakareanga ki te ℓ.
a=\frac{F}{ℓ}\text{, }a\neq 0
Tē taea kia ōrite te tāupe a ki 0.
F=ℓa
Whakareatia ngā taha e rua o te whārite ki te a.
