Why does the first one work while the second one is messed up?

\frac{2AB}{t^{&#039;}_A - t_A} = c

\frac{2AB}{{t^&#039;}_A - t_A} = c

How would i go about getting the Amp to space a few characters away from the t(not) symbol?
I = \sqrt {[\frac {22.6T + 0.088t -490.58} {5 * 10^{-5} * t}] * t_{0}} Amp

\frac{2AB}{{t^&#039;}_A - t_A} = c

Because you screwed up the code.Specifically,because your first code differs from the second through misplaced "{" which changes the way the "\frac" would work...

If you want it still farther away, use \qquad instead of \quad.

I posted this today in the cosmology forum:

dt = \frac{da}{H_0 \left(\frac{\Omega_{m,0}}{a} + a^2 \Omega_{\Lambda,0}\right)^{\frac{1}{2}}}

How can I made that the first "Omega" and "a" have the same size than the second?

 

[dextercioby]

U can't.Note that the whole fraction must be on equal footing a^{2}Omega...That means that the denominator & the numerator would be smaller than they'd be without the fraction line.

Daniel.

 

[robphy]

Use \displaystyle

dt = \frac{da}{H_0 \left(\displaystyle\frac{\Omega_{m,0}}{a} + a^2 \Omega_{\Lambda,0}\right)^{\frac{1}{2}}}

You probably wanted to put the extra backslash to escape the space {\rm\ } to get

You could just write it in an mbox

or in a verbatim environment

However, I think it is probably discouraged to post like this.

Whenever you want to include a graphic on the same line with your text, like C H_4 or G_\textrm{diffeo} or y = mx + b, you should use [ itex ]...[ /itex ] instead of [ tex ]...[ /tex ]. The "i" means "inline."

Click on each of the examples above to "learn by example."

If you have questions or comments about this site addition, you are welcome to post them here!

Good luck, and enjoy the system.

- Warren

I came looking specifically because my "inlines" were not in line. Glad to find this, but even with the itex the graphic is still raised. Is there a trick for lowering it more if you want to?

Edit

I am on a different machine now, and things look different. The inline text here does look inline. It is some local setting on my computer making the difference.

Problems with brackets:

\left(\begin{array}{cc}\frac{\partial u}{\partial x}&amp;\frac{\partial \nu}{\partial x}\\ \frac{\partial \nu}{\partial x}&amp;\frac{\partial u}{\partial x}\end{array}\right)

\phi(x,y)

\frac{\partial^2 \phi}{\partial u^2} + \frac{\partial^2 \phi}{\partial \nu^2} = 0

w = u(x,y) + i\nu(x,y)

\frac{\partial \phi}{\partial x} = \frac{\partial \phi}{\partial u} \frac{\partial u}{\partial x} + \frac{\partial \phi}{\partial \nu} \frac{\partial \nu}{\partial x}

and

\frac{\partial \phi}{\partial y} = \frac{\partial \phi}{\partial u} \frac{\partial u}{\partial y} + \frac{\partial \phi}{\partial \nu} \frac{\partial \nu}{\partial y}

A second differentiation of these yields the results:

\frac{\partial^2 \phi}{\partial x^2} = \frac{\partial \phi}{\partial u} \frac{\partial^2 u}{\partial x^2} + \left ( \frac{\partial^2 \phi}{\partial u^2} \frac{\partial u}{\partial x} + \frac{\partial^2 \phi}{\partial \nu \partial u} \frac{\partial \nu}{\partial x} \right ) \frac{\partial u}{\partial x} + \frac{\partial \phi}{\partial \nu} \frac{\partial^2 \nu}{\partial x^2} + \left ( \frac{\partial^2 \phi}{\partial u \partial \nu} \frac{\partial u}{\partial x} + \frac{\partial^2 \phi}{\partial \nu} \frac{\partial \nu}{\partial x} \right ) \frac{\partial \nu}{\partial x}

Adding:

\frac{\partial^2 \phi}{\partial x^2} + \frac{\partial^2 \phi}{\partial y^2} = \frac{\partial \phi}{\partial u} \left ( \frac{\partial^2 u}{\partial x^2} + \frac{\partial^2 u}{\partial y^2} \right ) + \frac{\partial^2 \phi}{\partial u^2} \left [ \left ( \frac{\partial u}{\partial x} \right )^2 + \left ( \frac{\partial u}{\partial y} \right )^2 \right ] + 2 \frac{\partial^2 \phi}{\partial u \partial \nu} \left ( \frac{\partial u}{\partial x} \frac{\partial \nu}{\partial y} \right ) + \frac{\partial \phi}{\partial \nu} \left ( \frac{\partial^2 \nu}{\partial x^2} + \frac{\partial^2 \nu}{\partial y^2} \right ) + \frac{\partial^2 \phi}{\partial \nu^2} \left [ \left ( \frac{\partial \nu}{\partial x} \right )^2 + \left ( \frac{\partial \nu}{\partial y} \right )^2 \right ]

w = u + i\nu

\frac{\partial^2 \phi}{\partial x^2} + \frac{\partial^2 \phi}{\partial y^2} = \frac{\partial^2 \phi}{\partial u^2} \left [ \left ( \frac{\partial \nu}{\partial x} \right )^2 + \left ( -\frac{\partial \nu}{\partial x} \right )^2 \right ] + \frac{\partial^2 \phi}{\partial \nu^2} \left [ \left ( \frac{\partial \nu}{\partial x} \right )^2 + \left ( \frac{\partial u}{\partial x} \right )^2 \right ] = \left [ \left ( \frac{\partial u}{\partial x} \right )^2 + \left ( \frac{\partial \nu}{\partial x} \right )^2 \right ] \left ( \frac{\partial^2 \phi}{\partial u^2} + \frac{\partial^2 \phi}{\partial \nu} \right ) = |f&#039;(z)|^2 \left ( \frac{\partial^2 \phi}{\partial u^2} + \frac{\partial^2 \phi}{\partial \nu^2} \right )

Just redefining an earlier problem I had (Do NOT pay attention to this! )

{\text{Let}} f_n \left( t \right) = \left\{ \begin{gathered} x_n \left( t \right) \hfill \\ y_n \left( t \right) \hfill \\ z_n \left( t \right) \hfill \\ \end{gathered} \right\} , {\text{ }} {\text{continuous}} {\text{ }} \forall t \in \left( {a,b} \right)

At any moment t \in \left( {a,b} \right), a triangle can be defined by the set of points \left\{ {f_1 \left( t \right),f_2 \left( t \right),f_3 \left( t \right)} \right\}.
Find the exact volume generated by this triangle from t = a to t = b.

a\xrightarrow{c}b

I can display things on top of arrows, but is it possible to display text under them (preferrably both above and below at the same time, actually)?

a \stackrel{c}{\longrightarrow} b


a \overset{c}{\longrightarrow} b

a \underset{d}{\longrightarrow} b

a \underset{d}{\overset{c}{\longrightarrow}} b

F=GmM_e/r^2

Edit: You added an unnecessary "\" before the F and G, and left out the necessary "/" in your second bracket.
