Equations and symbols.

How can I ask questions that need symbols and equations to explain?

 

use words to describe symbols

 

Write your question neatly on paper. Take a picture of the page. Upload the picture to the forum.

Doesn't this site have "Latex"?

 

I don't think so. When ever you write something using Latex, I can see only code.

this, for example:
"$ \sqrt {\frac {x^2}{3}} $" (without the spaces) renders as $\sqrt{\frac{x^2}{3}}$.

 

I have been saying this repeatedly.

 

On other sites [ tex ] [ \tex ] (without the spaces)
on some [ math ] [/math ]
and on yet others $ $
are used for Latex.

None of them seem to
\(\sqrt{x^2}\)
[math]\sqrt{x^2}[/math]
$\sqrt{x^2}$​

 

LaTex does not work here.

 

Trial: \(\sum_{n= 0}^\infty \frac{x^n}{n!}= e^x\).

\(\int_{-\infty}^\infty e^{-x^2}dx= \sqrt{2\pi}\).

Does not seem to work.

 

I don't know how to use LaTex.

 

Oh, it did work!

 

To get these I used
\sum_{n= 0}^\infty \frac{x^n}{n!}= e^x and
\int_{-\infty}^\infty e^{-x^2}dx= \sqrt{2\pi}[

between [ tex ] and [ /tex ] without the spaces.

There is a Latex tutorial at
LaTeX math and equations - LaTeX-Tutorial.com

 

Without spaces, huh? Let me try.

[ tex ]x^2+y^2[ / tex ]

 

$f(x) = x^2$

 

Matrices
\begin{matrix}
1 & 0\\
0 & 1
\end{matrix}


\begin{matrix}
1 & 0& 1\\
2 & 3& 1\\
4 & 5& 0
\end{matrix}

what f(x) = z? I was trying Latex for matrices
