Brief introduction to LaTeX .

Question

mathslover · Answer

LaTeX is like a language. A computer based language which allows us to post the equations in a good and suitable format. 

x^2/ 4 does not look good while : $\cfrac{x^2}{4}$ looks good.

Similarly , if we are having long equations : x^2 + 3x + 9 -x^3 /2 

I can write the same as : $x^2 +3x + 9 -\cfrac{x^3}{2}$ 

It also allows you to post some greetings , texts . Suppose you want to greet a person happy birthday, you will write : Happy Birthday! But if I write the same as : 

$\color{blue}{\cal{Happy} \space { Birthday!}} \ddot \smile $ 

It looks better. Basically , LaTeX is used for equations only, though many of the users use it as for textx greetings also. You can also write them in different sizes : 

$\begin{array}{} 
\tiny \textbf {hi}\
\scriptsize \textbf {hi}\
\small \textbf {hi}\
\textbf {hi}\
\large \textbf {hi}\
\Large \textbf {hi}\
\LARGE \textbf {hi}\
\huge \textbf {hi}\
\Huge \textbf {hi}\ 
\end{array}$ 

You can also use different colours to make LaTeX look beautiful . 

`\color{colorname}` 

Like : `$\color{blue}{\textbf {hi}}$ ` $\color{blue}{\textbf {hi}}$
