LaTeX Introducing LaTeX Math Typesetting

[chroot]

Hmmmmm. What browser are you using?

- Warren

 

[Hurkyl]

Opera 7.23

Sometimes they appear high like that, and sometimes they appear low.


Oh, and I get them in Netscape 7.0 too. (appearing low for the image I posted)

 

[chroot]

And this never used to happen in PF2? Does clicking on a latex image still bring up the little code dialog?

- Warren

 

[Hurkyl]

Never happened before the upgrade. And yes, I can still get the code popup.

 

[chroot]

Test... \beta

 

[Hurkyl]

And there still be a dash. It's low.

 

[chroot]

Test... \sqrt{x} \{sqrt}{x}

 

[chroot]

Testing... E = -grad\Phi

 

[chroot]

Testing... E = \grad\Phi

 

[chroot]

Testing... E = mc^2<br /> E = -grad\Phi

 

[chroot]

Testing.. \sqrt x

 

[Hurkyl]

still dashes. All low.

 

[chroot]

Hurkyl,

I'm afraid it really may just be a bug in your browser.

- Warren

 

[Hurkyl]

The dash goes away if I take out the anchor tag.

Oddly, if I change "<a href..." to "<b href..." it shows up fine.

 

[chroot]

Right, your browser is not obeying the border=0 attribute on the images for some reason -- likely because of a style sheet or other bug.

- Warren

 

[chroot]

Test... \infty

 

[JohnDubYa]

I am just testing the new LateX engine.

x = \int_\infty^0 \sin(\cos(\theta)) \,dx \frac{e^x}{\log(x)}

 

[hughes johnson]

e=mc^2
f=ma

Blah, blah, blah

 

[Hurkyl]

Hey, I don't see the dashes today. Woohoo! (I wonder how long it's been?)

latex display size

Is there a way to force this to be displayed bigger:

{ a^{log_cb} = b^{log_ca}

and is there a way to make it clearer that c is a base?

 

[chroot]

Use an \mbox{} to step out of the default format, then use one of the font size commands to set the desired size.

\mbox{\large a^{\log_cb} = b^{\log_ca}}
\mbox{\Large a^{\log_cb} = b^{\log_ca}}
\mbox{\LARGE a^{\log_cb} = b^{\log_ca}}
\mbox{\huge a^{\log_cb} = b^{\log_ca}}
\mbox{\Huge a^{\log_cb} = b^{\log_ca}}

[chroot]

Hey, I don't see the dashes today. Woohoo! (I wonder how long it's been?)

Whoops, I forgot to tell you I fixed that...

- Warren

 

[PRyckman]

Wow, I'd like to be involved in this but all those formulas are greek to me, the symbols.
I can't handle stuff like that, throughout school I was always daydreaming. I did well on the tests because I understood not because I studied. Eventually that was way to much for me though. But I never gave up on physics. I stuck to the theoretical side, there are many things left to prove. My mind always focused on the vastness of space, it's intricisies(sp?) It's explained and it's not. Since I heard E=mc2 I never doubted it. I took it as fact and thought about what it could mean. Where it's explanation stopped, and it's implications began.

So, Sorry I can't give any cool input on your thread chroot :) :P

I really appreciate your thought into mine though. Because like I said my math isn't as advanced as yours. I would never be able to prove anything if I can't get someone to help me.

 

[chroot]

We're not discussing anything in this thread, PRyckman. It started as a tutorial of PF's LaTeX math typesetting, and turned into a test thread. People are just posting random equations to learn how the typesetting works.

- Warren

 

[PRyckman]

yes i read the first 20 posts or so only and last 5 or 10

Why is this fraction not displaying correctly?

\mbox{\Huge B = \frac{1}{15} }

 

[Sauter]

<br /> \newcount\n<br /> \n=1<br /> \def\abc#1{<br /> \ifnum\n&lt;#1<br /> \the\n \par<br /> \advance\n by 1<br /> \abc{#1}<br /> \fi<br /> }<br /> \abc{10}<br />

 

[Sauter]

Why is this fraction not displaying correctly?

\mbox{\Huge B = \frac{1}{15} }

\Huge B = \frac{1}{15}

 

[Sauter]

Why is this fraction not displaying correctly?

\mbox{\Huge B = \frac{1}{15} }

\mbox{\Huge B = $\frac{1}{15}$ }

 

[IooqXpooI]

Ehehehe.

\mbox{\Huge \frac{U_4^{T_1}}{\frac {M_0}{P_v(M_4)}}}

textogif

This is my first attempt to use tex locally.
I'm trying to produce a .gif or .png image of a tex-formatted equation.

I created this file, named logic1.tex:

\documentclass{article}
\begin{document}
\begin{flushleft}
\begin{displaymath}
\pi \models \phi \Rightarrow \psi \:\textrm{iff}\:\pi \not\models \phi \:\textrm{or}\:\pi \models \psi 
\end{displaymath}
\end{flushleft}
\end{document}

When I run
>latex logic1.tex
it produces logic1.dvi which I can view with the kdvi viewer & it appears to be correct. But when I run
>textogif logic1.tex
or
>textogif -png logic1.tex
the resulting image file has the equation superimposed over a checkerboard-pattern background which makes it virtually impossible to read.

What am I doing wrong?

How about my logic1.tex file: is anything missing or extraneous?

 

[chroot]

The checkerboard pattern is the "standard" way to show that parts of an image are transparent. Try including the image in a web page to see how it looks.

- Warren

 

[gnome]

Thanks Warren.

But then, how can I make a png or gif image with a plain white background that I can send someone, to be opened with an ordinary viewer (not on a web page)?

 

[chroot]

Use one of the many utilities available for changing gif (or png) color tables.

V_e = \frac{c[v_1 - (v_1 - x)]}{v_1 + (v_1 - x)}



V_e = \frac{c[v_1 - (v_1 - x)]}{v_1 + (v_1 - x)}

V_e^2 \equiv \frac{c^2x^2}{(2v_1-x)(2v_1-x)}



\gamma \equiv \frac{1}{\sqrt{1 - v^2/c^2}}

Please take a look at post #4 on this thread

and tell me what I should have done to make the line spacing and font size more consistent.

[Hurkyl]

Believe it or not, the font size is consistent.

If you want better spacing, maybe you could put all of the equations in a single tex tag. Check the first page for an example.

 

[chroot]

Edwin,

Since you seem to be addicted to nesting pieces of TeX inside other pieces of TeX, I will advise you that you can use whitespace inside the [ tex ] tags to make your code easier to write (and read). In other words, code like this is fine (click the image to see the code):

\frac{<br /> \frac{3}{4}<br /> }{<br /> \frac{1}{2}<br /> }

- Warren

 

[Edwin]

Thanks Warren! That was a helpful bit of information :)


Best Regards,

Edwin

 

[Hurkyl]

If you're still working on your TeX identifier for the newsgroups, here's a good one to tweak it on:

[justintime]

let me have a try!
a=b^3

 

[BobG]

We'll give it a try (doesn't look to promising in preview mode) But it almost works once posted.


\ddot\lambda + \omega^2_E \left(\frac{R_E}{a}\right)^2

Now, that's what we're looking for. Takes a little time to get the feel for the order and size, etc.

 

[chroot]

Bob:

It should work just fine in preview mode. Some browsers may cache images, and you may have to force them not to.

[arildno]

Hi, I have a question concerning the following Latex/(Tex?) commands:
I tried to make a listing with the following command structure (within the environment delimited by the tex-brackets):
\begin{enumerate}
\item ...
\item ...
\end{enumerate}
This has for me always produced a numbered list for each \item included,
but when I tried it on PF, the numbers failed to appear, and the items did not appear on separate lines
(A similar result was with "itemize" rather than "enumerate", which usually have produced dots rather than numbers in front of the items included)

So, what's the listing commands I should use here?

 

[Vance]

\ddot\lambda + \omega^2_E \left(\frac{R_E}{a}\right)^2

 

[Vance]

Copy and paste works fine

 

[Vance]

I would like to make a question:
I know of Latex when using Linux system of my school, but there isnot Latex for Windows, right ? If I would like to practise learning Latex but in Windows, that is impossible right ?

Please help me, please forgive my newie question because I am actually a newie...Please...
:)
Thanks in advance

 

[chroot]

Look into a package called MikTeX for windows.
