LaTeX Introducing LaTeX Math Typesetting

[Tron3k]

Just figuring this out...

y = a x^2 + b x + c
x = \frac{-b \pm \sqrt{b^2 - 4 a c}}{2 a}

 

[Silverious]

hmmmm

d = \frac{1}{2}a t^2

\sum F = ma

\lim_{x\rightarrow c} f(x) = L

0 \leq |x - c| \leq \delta

|f(x) - L| \leq \epsilon

F_g = G \frac{m_1 m_2}{d^2}

this = fun

 

[Allegro]

Let's give it a try (using TexAide):

\frac{{\sqrt s }}{{s - a^2 }}<br />





\displaystyle{\int_2^4 {\left[ {8(t - 2)} \right]^{-0.5} dt = } \left[ {\frac{1}{{\sqrt 2 }}(t - 2)^{0.5} } \right]_2^4 = 1}


With compliments to TeXaide.

 

[phoenixthoth]

how do i go about installing such a thing on my discussion forum? any help much appreciated!

 

[Allegro]

TeXaide

Hello phoenixthoth,

#1.
Download TeXaide:
http://www.mathtype.com/en/products/TeXaide/

#2.
Type in an equation in TeXaide and copy it.

#3
Paste it in your message on the Physics Forum,then go to my previous message and click on quote,then you can see how it is done.

Delete all superfluous characters.


Best regards.

how do i go about installing such a thing on my discussion forum? any help much appreciated!

thanks for trying to help but that wasn't my question. let me try to be more careful.
0. i already know how to make equations appear on this forum.
1. i have my own discussion forum.
2. i want to install something that will enable me to do what i can do on this forum on that forum.

i tried mimetex (from http://www.forkosh.com/htdocs/mimetex.html), but I'm having trouble compiling their source files into a mimetex.cgi file. it would help trememdously to just have a copy of that cgi file in question so that i can put it on my server. when i tried compiling their source files, i got a bunch of errors that i suspect are related to the fact that I'm running windows or perhaps the compiler I'm using. I'm trying to get the anti-aliasing gif version to work by entering
cc -DAA mimetex.c gifsave.c -lm -o mimetex.cgi
but it gives lots of errors.

so if you know anything on how to install an equivalent gif generator that uses html, let me know. any help is appreciated!

 

[Hurkyl]

Oh no! The inline TeX no ^longer is aligned!

 

[chroot]

What in the world are you doing? It works fine for me... \vec F = m \vec a

And how about this? \TeX

If you put random text in, though... hmmm who knows?

[Hurkyl]

It's because I've written superscripted normal text.

Oh, of course... hmmm, yeah. There's really no way around that.

There really isn't any reason you would want superscripted text and tex in the same message anyway.

 

[Hurkyl]

I put a footnote in one of my messages. I had an itex formula in it, and I tend to put my footnote tags in superscripts¹. Thus, the bug was discovered.



1: such as this one

 

[lethe]

what is going on with TeX today? is it broken?

see this thread

 

[lethe]

let's see if it works over here:

\int_M d\omega=\int_{\partial M}\omega

 

[chroot]

lethe, your link is apparently not valid. What is happening? As far as I know, \TeX is working fine.

this morning, it seemed like LaTeX wasn't working. i guess i linked to a post that i later deleted or something. i guess that is why the link i gave didn't work (although i don't think a broken anchor is usually enough to break a link, but whatever.)

anyway, try this link. look at matt grime's post near the bottom.

everywhere there should be a LaTeX image, intsead, you get "latex still being generated, please reload" messages. i was getting the same thing in my posts, which i later deleted in order to try to recify the problem.

at any rate, whatever the problem was, it seems to be fixed now, although you can still see the weird messages now.

 

[Hurkyl]

More misformatting

I can't figure out what's going on with this one (though I haven't tried a lot)

Using this theorem, if x^3 - x^2 - 8x + 12 has a rational root, then it can be written in the form p/q where p \in \{1, -1\} and q \in \{1, -1, 2, -2, 3, -3, 4, -4, 6, -6, 12, -12\}. Only 12 possibilities to try, so if one exists you can find it by exhaustion.

 

[chroot]

It seems to be due to the length of the itex element. I'll see if I can figure out what's up with it. In the meantime, please use the normal tex (not itex) tags to typeset this.

I've downloaded that pdf file with code instuctions, but there's no "non equal" sign .

Do you know the code (it's for slashed equal sign)?

[outandbeyond2004]

I thought Latex did not work, but it did. The trouble seems to be with the Review message function. try \pm8 and hit the check button. it is supposed to be plus-minus 8, but comes out f1 8. Latex does work after you send the message, tho.

[Clausius2]

Anyone knows where can I download LaTex as a ZIP file? My download rate is too slow.

 

[Philcorp]

Ok. I've been trying to know how to make a lower case script r (for example, like in Griffiths' Electrodynamics book) for about a year now...i was wondering if anyone around here maybe knew how?

 

[JohnDubYa]

This board is another reason PHYSICS RULES!

Okay, I have to try this out

\int_\infty^0 \frac{\partial x}{\partial t}\,dx

 

[JohnDubYa]

He wants a script r. I am not sure how Griffith's r's look, but have you tried the calligraphic style?

Try R_{\cal R}


Try [ tex ]R_{\cal R}[ \tex ]

I don't think it works with lowercase.

You have to use a forward slash ( / ). It won't work if you use back slash ( \ ).

[Hurkyl]

LaTeX doesn't seem to work yet in the new forums.

 

[Greg Bernhardt]

chroot still needs to install it, hopefully tonight

 

[JohnDubYa]

I still want this LaTeX capability for my own discussion boards for helping students with remedial math. Is it available? Can I buy it?

 

[chroot]

It's custom-designed, by me. If you'd like to contract me to work on your site, send me a PM...

Why are we getting these extra dashes?

[chroot]

What extra dashes?

- Warren

 

[Hurkyl]

These dashes.

 

[chroot]

Hurkyl,

That's kinda funny. I don't see those dashes in my browser. Can you right click on a latex image and view it by itself in a new window? Do the dashes still appear there?

- Warren

 

[Hurkyl]

Nope.


BTW, someone else mentioned also having this problem, I don't remember who.
