Whakaoti i te S=(w^2*r)*(w^2*r_{1})

$$S = ( w ^ { 2 } \cdot r ) \cdot ( w ^ { 2 } \cdot r _ { 1 } )$$

Whakaoti mō r

$$\left\{\begin{matrix}r=\frac{S}{r_{1}w^{4}}\text{, }&r_{1}\neq 0\text{ and }w\neq 0\\r\in \mathrm{R}\text{, }&\left(r_{1}=0\text{ or }w=0\right)\text{ and }S=0\end{matrix}\right.$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Hei whakarea i ngā pū o te pūtake kotahi, me tāpiri ō rātou taupū. Tāpiria te 2 me te 2 kia riro ai te 4.

$$S=w^{4}rr_{1}$$

Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.

$$w^{4}rr_{1}=S$$

He hanga arowhānui tō te whārite.

$$r_{1}w^{4}r=S$$

Whakawehea ngā taha e rua ki te w^{4}r_{1}.

$$\frac{r_{1}w^{4}r}{r_{1}w^{4}}=\frac{S}{r_{1}w^{4}}$$

Mā te whakawehe ki te w^{4}r_{1} ka wetekia te whakareanga ki te w^{4}r_{1}.

$$r=\frac{S}{r_{1}w^{4}}$$

Whakaoti mō S

$$S=rr_{1}w^{4}$$

Ngā Upane Otinga

Hei whakarea i ngā pū o te pūtake kotahi, me tāpiri ō rātou taupū. Tāpiria te 2 me te 2 kia riro ai te 4.

$$S=w^{4}rr_{1}$$
