In first-year calculus, we   define intervals  such as
$(u, v)$ and $(u, \infty)$.  Such an interval is a
\emph{neighborhood} of  $a$
if  $a$ is in the interval.  Students should
realize that  $\infty$ is only a
symbol, not a number.  This is important since
we soon introduce concepts
 such as $\lim_{x \to \infty} f(x)$.
 
When we introduce the derivative,
\[
   \lim_{x \to a} \frac{f(x) - f(a)}{x - a},
\]
we assume that the function is defined and continuous
in a neighborhood of $a$.

And here are two ways to create active links in \LaTeX:

\url{http://www.csun.edu/~hfmth009}

\href{http://www.csun.edu/~hfmth009}{CSUN's Math Dept}

Both of them point to CSUN's Math Dept.

And here is verbatim environment, useful in program listing:
\begin{verbatim}
LaTeX markup command for sine function is  \sin x

How to form inline math expression:
$\sin x
How to form displayed math expression:
\[
\sin x
\]

hhhhhhhh   kkkkkkkkkkkkkkkkkk

jjjjjjjjjjjjjjjjjjjjjjjjjjjjjjj

BLAH, blah............
\end{verbatim}

And that is all!

LaTeX Applet Help (pdf version)

Hints on using Latex Equation Editors:

Place your cursor in LaTeX input window where you want to insert math expression;
Check inline box in Latex Equation Editor window to produce inline math expressions;
Use the displayed menus/buttons to create your math expression;
Watch it being displayed;
Use Copy to Document button to copy your expression to the LaTeX input window.

And here is a new (improved) version of the above LaTeX Equation Editor:

Important notes:

Use of LaTeX Equation Editors is OPTIONAL and is NOT needed for typesetting process.

If you don't use LaTeX Equation Editors, you may prefer another version of this applet with larger area for LaTeX input:

Click on Typeset button to run LaTeX.
