sinx=h/1.4 eching

$$\sin x = \frac { h } { 1.4 }$$

h uchun yechish

$$h=\frac{7\sin(x)}{5}$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

Tomonlarni almashtirib, barcha oʻzgaruvchi shartlar chap tomonga oʻtkazing.

$$\frac{h}{1,4}=\sin(x)$$

Tenglama standart shaklda.

$$\frac{5}{7}h=\sin(x)$$

Tenglamaning ikki tarafini \frac{5}{7} ga bo'lish, bu kasrni qaytarish orqali ikkala tarafga ko'paytirish bilan aynidir.

$$\frac{\frac{5}{7}h}{\frac{5}{7}}=\frac{\sin(x)}{\frac{5}{7}}$$

\frac{5}{7} ga bo'lish \frac{5}{7} ga ko'paytirishni bekor qiladi.

$$h=\frac{\sin(x)}{\frac{5}{7}}$$

\sin(x) ni \frac{5}{7} ga bo'lish \sin(x) ga k'paytirish \frac{5}{7} ga qaytarish.

$$h=\frac{7\sin(x)}{5}$$

x uchun yechish

$$x=-\arcsin(\frac{5h}{7})+2\pi n_{1}+\pi \text{, }n_{1}\in \mathrm{Z}$$

$$x=\arcsin(\frac{5h}{7})+2\pi n_{2}\text{, }n_{2}\in \mathrm{Z}\text{, }|h|\leq \frac{7}{5}$$
