x=y*cos(z) eching

$$x=y \times \cos ( z )$$

y uchun yechish

$$\left\{\begin{matrix}y=\frac{x}{\cos(z)}\text{, }&\nexists n_{1}\in \mathrm{Z}\text{ : }z=\pi n_{1}+\frac{\pi }{2}\\y\in \mathrm{R}\text{, }&x=0\text{ and }\exists n_{1}\in \mathrm{Z}\text{ : }z=\pi n_{1}+\frac{\pi }{2}\end{matrix}\right,$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

Tomonlarni almashtirib, barcha oʻzgaruvchi shartlar chap tomonga oʻtkazing.

$$y\cos(z)=x$$

Tenglama standart shaklda.

$$\cos(z)y=x$$

Ikki tarafini \cos(z) ga bo‘ling.

$$\frac{\cos(z)y}{\cos(z)}=\frac{x}{\cos(z)}$$

\cos(z) ga bo'lish \cos(z) ga ko'paytirishni bekor qiladi.

$$y=\frac{x}{\cos(z)}$$

x uchun yechish

$$x=y\cos(z)$$
