Whakaoti i te 1=2pisqrt{x/9.81}

$$1 = 2 \pi \sqrt{ \frac{ x }{ 9.81 } }$$

Whakaoti mō x

$$x=\frac{981}{400\pi ^{2}}\approx 0.248490203$$

Ngā Upane mō te Whakaoti Whārite Pūtake

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

$$2\pi \sqrt{\frac{x}{9.81}}=1$$

Whakawehea ngā taha e rua ki te 2\pi .

$$\frac{2\pi \sqrt{\frac{100}{981}x}}{2\pi }=\frac{1}{2\pi }$$

Mā te whakawehe ki te 2\pi ka wetekia te whakareanga ki te 2\pi .

$$\sqrt{\frac{100}{981}x}=\frac{1}{2\pi }$$

Pūruatia ngā taha e rua o te whārite.

$$\frac{100}{981}x=\frac{1}{4\pi ^{2}}$$

Whakawehea ngā taha e rua o te whārite ki te \frac{100}{981}, he ōrite ki te whakarea i ngā taha e rua ki te tau huripoki o te hautanga.

$$\frac{\frac{100}{981}x}{\frac{100}{981}}=\frac{1}{\frac{100}{981}\times 4\pi ^{2}}$$

Mā te whakawehe ki te \frac{100}{981} ka wetekia te whakareanga ki te \frac{100}{981}.

$$x=\frac{1}{\frac{100}{981}\times 4\pi ^{2}}$$

Whakawehe \frac{1}{4\pi ^{2}} ki te \frac{100}{981} mā te whakarea \frac{1}{4\pi ^{2}} ki te tau huripoki o \frac{100}{981}.

$$x=\frac{981}{400\pi ^{2}}$$
