i have a question regarding tex, before tex was invented, how did scientists published equations through the internet?
\binom{}{} requires the amsmath package.Pakistani_Shikra said:can anyone tell me how to use binomial in laTeX bcoz when i use \binom it doesn't comes up with anything except = mn
can anyone explain this to me ??

Your \begin{picture} command has curly brackets after it {60,60} instead of round (60,60)VietDao29 said:This is driving me crazy... Does anyone know why there's a text 0, 60 in the third picture? I didn't put any text there, it just appeared mysteriously...
Ah, yes, thanks a lot. Sometimes, I just mess up the round bracket, and the curly ones.J77 said:Your \begin{picture} command has curly brackets after it {60,60} instead of round (60,60)
You forgot to type in the '}' at the end.pavadrin said:[tex] \frac{\pi ^2^2^2}{\log \cos \sin \tan [/tex]
Water said:I'm having trouble trying to write mass times specific heat times delta T subscript copper to represent the internal energy of a piece of copper. This was one of my many unsuccessful attempts:
[tex]mc /Delta T_{copper}[/tex]
How do you do it?
sylas said:I am wanting to preview a post containing tex. But the preview tells me that it is being generated, and when I refresh to see the result, it then restarts the generation process.
I think.
Is there any way I can preview my tex before posting?
Thanks -- Sylas.
oen_maclaude said:i guess there is something wrong in the pdf file in
https://www.physicsforums.com/misc/howtolatex.pdf
it should be /tex not \tex
mbrmbrg said:This post rather befuddled me, b/c I learned from that file and never had a problem...
Then I saw it--
although [ t e x ]...[ / t e x ] does appear twice., [ t e x ]...[ \ t e x ] appears once.
It's all in what you look for !
BTW, can anyone explain the itex [itex]\frac{7 days}{1 week}[/itex] vs tex [tex]\frac{7 days}{1 week}[/tex] deal?
oen_maclaude said:i guess it is better for articles to be consistent. just a thought. Anyway, thanks!
loop quantum gravity said:hi, I am using texniccenter, and i would appreciate if someone could sopt my errors in my code, and help me correct it.
here's the code:
\begin{normalsize}
\begin{document}
\begin{equation}
\normalsize
m\int\limits_{x_1}^{x_2}
\frac{dv}{dt}dx=\int\limits_'{x_1}^{x_2}F(x)dx

dx=\frac{dx}{dt}dt=vdt
\nonumber\\
m\int\limits_{x_1}^{x_2}\frac{dv}{dt}dx=m\int\limits_{t_1}^{t_2}\frac{dv}{dt}vdt
\nonumber\\
=\int\limits_{t_1}^{t_2}\frac(d}{dt}
(\frac{1}{2}v^2)dt=\frac{1}{2}m[v_2^2-v_1^2]
