Introducing LaTeX Math Typesetting

Nope. It seems to make no difference whether I format it using {array}{cc} or {array}{11} or {equation*}{split}, \mbox{...} or \text{...]. For example:

To accomplish this, the formula will be built up from 3 types of variables, specifically:
[tex]\begin{array}{11}\mbox{Variable} & \mbox{Meaning}\\
Q[i,k] &\mbox{At time i, M is in state q_k}\\
H[i,j] &\mbox{At time i, the read-write head}\\
&\mbox{ is scanning tape square j}\\
S[i,j,k] &\mbox{At time i, the contents of}\\
&\mbox{tape square j is symbol s_k}\end{array}[/tex]

It's not a 1 it's an 'l' and you need one for each row:

edited to add: hmm I can't see anything wrong with this perhaps it's just too big.

gnome

(I think it's just any series of characters {xxx}, {111}, {iii}, whatever, not some particular one; and isn't it one for each COLUMN, not row?)


Edited to remove my witty(?) remark about the part of your post that you deleted.

jcsd

No, it's one for each row and 'c' is for centre 'l' is for left I guess.

edited to add: actually you're right but {ll}, {cc} or {rr} is the justifcation.

This one works and it's simlair:

[tex]\begin{array}{lr}\mbox{yoink}&\mbox{double-yoink}\\G[i,j]&\mbox{yes}\\H[k,l] &\mbox{no}\\&\mbox{what?}\end{array}[/tex]

I reckon then it must be thta it's just too big as there's a limit to the size of the code.

gnome

Good find!!

That should be helpful.

gnome

That's it!!!!!!!!

[tex]\begin{array}{ll}\mbox{Variable} & \mbox{Meaning}\\
Q[i,k] &\mbox{At time i, M is in state}\, q_k\\
H[i,j] &\mbox{At time i, the read-write head}\\
&\mbox{is scanning tape square j}\\
S[i,j,k] &\mbox{At time i, the contents of}\\
&\mbox{tape square j is symbol}\, s_k\end{array}[/tex]


[tex]\mbox{testing another sub_sc_rip_t}[/tex]

Building on jcsd's find:
the charaters in the brackets after {array} must be
{lll} (that lower-case L's) to left-align
{rrr} to right-align
{"any characters"} to center the text in each column (one char for each column)

Also: apparently subscript like q_k can't be used in \mbox in an array, although it can be used in \mbox when it's not part of an array.

Now I can get back to my "real" post.

Thanks.

Wick Contraction-

http://www.fzu.cz/~kolorenc/tex.php

This website has 2 or 3 possible implementations for Wick Contractions in QFT. I have not tried any, but will let you know how they work!

Hi everybody,
Does anyone know how do I write a vector quantity, such as an F with an arrow up? I'm not so skilled in Latex.
Thanks

jcsd

\vec{F}

[tex]\vec{F}[/tex]

ramollari

OK, let me try once.

[tex]
\sum\vec{F}_e_x_t = M\vec{a}_c_m
[/tex]

Thanks jcsd!

How do I create the 'inverse' symbol?

z-component

Like [tex]cos\theta^{-1}[/tex]?

jcsd

inverse is just ^{-1}, so the (muplicative) inverse of a is a^{-1}, for an inverse function like cos you want \cos^{-1}\theta

[tex]\begin{array}P=A(1+\frac{r}{100})^n
\\
\sqrt[n]{\frac{P}{A}}=\frac{r+100}{100}
\\
r=100\sqrt[n]{\frac{P}{A}}-100\end{array}[/tex]

The simple_wick.tex file works very well. I could not get the other one to work. I also did not have any of the problems the author gives for simple_wick.tex.

Cheers
