Tohaina
Kua tāruatia ki te papatopenga
\frac{1}{f}=a
Whakaraupapatia anō ngā kīanga tau.
1=af
Tē taea kia ōrite te tāupe f ki 0 nā te kore tautuhi i te whakawehenga mā te kore. Whakareatia ngā taha e rua o te whārite ki te f.
af=1
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
\frac{af}{a}=\frac{1}{a}
Whakawehea ngā taha e rua ki te a.
f=\frac{1}{a}
Mā te whakawehe ki te a ka wetekia te whakareanga ki te a.
f=\frac{1}{a}\text{, }f\neq 0
Tē taea kia ōrite te tāupe f ki 0.
