Whakaoti i te r=a(999-sinθ)

$$r = a ( 999 - \sin \theta )$$

Whakaoti mō a

$$a=-\frac{r}{\sin(\theta )-999}$$

Ngā Upane mō te Whakaoti Whārite Rārangi

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

$$a\left(999-\sin(\theta )\right)=r$$

Whakamahia te āhuatanga tohatoha hei whakarea te a ki te 999-\sin(\theta ).

$$999a-a\sin(\theta )=r$$

Pahekotia ngā kīanga tau katoa e whai ana i te a.

$$\left(999-\sin(\theta )\right)a=r$$

He hanga arowhānui tō te whārite.

$$\left(-\sin(\theta )+999\right)a=r$$

Whakawehea ngā taha e rua ki te 999-\sin(\theta ).

$$\frac{\left(-\sin(\theta )+999\right)a}{-\sin(\theta )+999}=\frac{r}{-\sin(\theta )+999}$$

Mā te whakawehe ki te 999-\sin(\theta ) ka wetekia te whakareanga ki te 999-\sin(\theta ).

$$a=\frac{r}{-\sin(\theta )+999}$$

Whakaoti mō r

$$r=-a\left(\sin(\theta )-999\right)$$
