Introducing LaTeX Math Typesetting

[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... $E = mc^2 E = -grad\Phi$

 

[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.

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

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

[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]

$$\newcount\n \n=1 \def\abc#1{ \ifnum\n<#1 \the\n \par \advance\n by 1 \abc{#1} \fi } \abc{10}$$

 

[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.

[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.

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



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

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



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

[tex]V_e=v[\tex]

Please take a look at post #4 on this thread
https://www.physicsforums.com/showthread.php?p=203474#post203474
and tell me what I should have done to make the line spacing and font size more consistent.
