r=a(999-sinθ) eching

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

a uchun yechish

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

Chiziqli tenglamalarni yechish bo'yicha qadamlar

Tomonlarni almashtirib, barcha oʻzgaruvchi shartlar chap tomonga oʻtkazing.

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

a ga 999-\sin(\theta ) ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

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

a'ga ega bo'lgan barcha shartlarni birlashtirish.

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

Tenglama standart shaklda.

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

Ikki tarafini 999-\sin(\theta ) ga bo‘ling.

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

999-\sin(\theta ) ga bo'lish 999-\sin(\theta ) ga ko'paytirishni bekor qiladi.

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

r uchun yechish

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