I have not read the whole thread ( I apologize) and I am totally new to Latex.
Typing the latex and memorizing the language sounds like a lot of work. I wonder if there is any shareware or freeware program with which I can write the equations by drag and drop and have the program write the latex for me.
I'll appreciate your help.

It's not really a whole lot of work. Start small and learn as you go. There are really only a handful of structures you need to know in order to get started. Learn by example: you can click on any equation posted in any thread and see what the person typed to create that image.

Another option I think may be the Equation Object included in WinWord which can also be somewhat similar help for you...(smiling)

I believe that the Equation Editor does not export LaTeX.
One has to use MathType http://www.dessci.com/en/products/mathtype/.


Other LaTeX editors
WinEdt http://www.winedt.com/
WinTeX http://www.tex-tools.de/main.html
WinShell http://www.winshell.de/

Maple and Mathematica can also export LaTeX.

Thanks guys for your information,
MathType sounds interesting. But as it costs $119, I downloaded TeXaid (form the same company). I'll explore the other products when I have the time.
I am a little confused by the statement on some of these products that they are not a LaTex system. It appears that you need two pieces of software that will work in conjucntion but I still don't understand what each one does.
I think TexAid should allow me to produce LaTex code to paste into the forum.
When I register for classes in fall, I'll buy Mathematica at academic price.
Thanks again,
--Alex--

Before buying Mathematica, ask in your University about it. Many universities have campus-wide licenses that allow students to use Mathematica from the University's network, and it is often the case that such benefits are not "common knowledge" among students.

<br /> \int_{2}^{3} \frac{\arctan}{\sqrt{a^2 + x^2}}dx<br />...lol...Thanks jcsd...that was a really dumb mistake

 

[jcsd]

You need to produce your equation you need to write:

\int_{2}^{3} \frac{\arctan}{\sqrt{a^2 + x^2}}dx<br />

 

[Alem2000]

yeah i got it...thanks a million...that was going to drive me crazy

 

[Alem2000]

<br /> \lim_{x\rightarrow \0} \sumf(x)\Delta = \int_{a}^{b}f(x) dx<br />

 

[Almeisan]

Does anyone know how I can get this to work locally with windows. I downloaded a couple of programs and I didn't really get any of them to actually show the fomulas.

<br /> \int_{0}^{h} \frac{1}{2\sqrt{hx}} dx = <br /> \frac{1}{2\sqrt{h}}(2x^\frac{1}{2}) \vert_{0}^{h} = 1

 

[robphy]

You'll need a LaTeX distribution (for example, www.miktex.org).
Basically, you take the latex file (file.tex) and run latex on it.
You get file.dvi, which can be viewed in a dvi viewer (called yap in miktex).

integral as an exponent

Hi, I am trying to use latex to display a math problem but I am having a little trouble getting started, and the function I want to display is a little bit weird.

I(x) = e^ (the integral of -tan x dx)

I am not even sure it can display an integral as an exponent, but I seem to be having plenty of trouble just getting it to display e!

Thanks in advance for your help!

I(x)=e^{-\int tanx\:dx}

 

[Math Is Hard]

woo hoo! muchas gracias, master coda!

 

[TALewis]

Or even better, use \tan to make the tangent function to appear in upright letters:

e^{- \int \tan x \, dx}

 

[master_coda]

I knew it didn't quite look right. And I was looking so smart, too.

 

[Math Is Hard]

They both look lovely. And it helped me get my math question answered. Thanks!

This is a test. I am pasting LaTex code from TexAide. Let's see if it works.

[alexepascual]

OK, It didn't work.
I believe the text with percent signs at the beginning should be comments. I hope that is not interfeering.
But I do have the Latex code enclosed in the Latex delimiters. So, what's wrong?
I'll appreciate your help.
I'll next post just the LaTex part (to reduce the number of variables) and see what happens.

Alex,

The tags are [ tex ] and [ /tex ], not [ tex ] and [ \tex ]. Forward slash, not backslash.

Thanks, Warren
Let's see:
<br /> \left\langle {\phi }<br /> \mathrel{\left | {\vphantom {\phi \Psi }}<br /> \right. \kern-\nulldelimiterspace}<br /> {\Psi } \right\rangle = \int {\phi ^ * } \left( x \right)\psi \left( x \right)dx<br />
Great!
