Natija : 6.3.FORMULA RAQAMLASH
Natija: Misol

Natija:

Biz bu erda tanlangan formulalar uchun harfalarni birbirga yaqin qilib
yozamiz.
\documentclass{article}
\usepackage{amsmath}
\begin{document}
$$
\begin{array}{l}
\frac{\ds\partial \varphi \left( {t,x} \right)}{\ds\partial t}=-\frac{\ds\partial
}{\ds\partial x}\left[ {\mu x\varphi \left( {t,x} \right)} \right]+\frac{\ds 1}{\ds
2}\frac{\ds\partial ^2}{\ds\partial x^2}\left[ {\sigma ^2x^2\varphi \left( {t,x}
\right)} \right],
\\
\left. {\varphi \left( {t,x} \right)} \right|_{t=0} =\varphi _0 \left( x

6.3.FORMULA RAQAMLASH
Matematik matnlarda, odatda, mos yozuvlar qulayligi uchun formulalarni
raqamlash kerak; LaTeX bu raqamni formulalar raqamlari va ularga havolalar
avtomatik ravishda ishlab chiqariladigan tarzda tashkil etishga imkon beradi.
Buning uchun quyidagi formulani belgilash kerak:
\begin{equation}
\end{equation}
orasidagi har qanday joyda \label buyrug‘i qo‘yiladi va \ref buyrug‘i formula
raqamini yaratadi.
Misol:
\documentclass{article}
\usepackage{amsmath}
\begin{document}
\begin{equation}
i^2 = -1.
\label{eq:ref}
\end{equation}
Bu yerda havola --- (\ref{eq:ref}).
\end{document}
Natija:
Misol:
\documentclass{article}
\usepackage[T2A]{fontenc}

\usepackage[utf8]{inputenc}
\usepackage[russian,english]{babel}
\usepackage{autonum}
\begin{document}
Raqamsiz formula:
\begin{equation}
i^2 = -1.
\end{equation}
Raqamli formula:
\[
i^2 = -1.
\label{eq:ref}
\]
Bu yerda havola --- (\ref{eq:ref}).
