New LaTeX Feature

  • Imagine you are sipping tea or coffee while discussing various issues with a broad and diverse network of students, colleagues, and friends brought together by the common bond of physics, graduate school, and the physics GRE.

New LaTeX Feature

Post by Grant » Wed Dec 30, 2009 5:15 pm

Today I added a new LaTeX feature. I added it along side the existing bbcodes like bold, italic, underline, quote, etc. For example, typing the following gives the result shown below:

Code: Select all

[tex]f(x)=\int_{-\infty}^xe^{-t^2}dt[/tex]
$$f(x)=\int_{-\infty}^xe^{-t^2}dt$$

I good resource to learn how to do LaTeX is found here:
http://en.wikipedia.org/wiki/Help:Displaying_a_formula

Also, if you right click and look at the properties of a LaTeX image on physicsgre.com you can see the code used to generate the LaTeX image.

$$\nabla \cdot \mathbf{E} &= \frac{\rho}{\epsilon_0}$$
$$\nabla \cdot \mathbf{B} &= 0$$
$$\nabla\times\mathbf{E} &= -\frac{\partial \mathbf{B}}{\partial t}$$
$$\nabla\times\mathbf{B} &= \mu_0 \mathbf{J} + \mu_0\epsilon_0\frac{\partial \mathbf{E}}{\partial t}$$

wooooo!
$$i\hbar\frac{\partial}{\partial t}\psi = H\psi$$

Eh do we really need this fancy stuff? LaTeX should be reserved for "play" only. We have no hope of truly understanding physics if we can't easily decipher good old formulas written in ordinary text...

[-(hbar^2)/2m] (d2_dx2)(psi_n) + V(x) (psi_n) = E_n (psi_n)

div(E) = ro / Epsilon_0

Integral(sqrt[x]sin(x^2)exp(-gamma*x^2), x E {-pi, pi})

Lol just kidding. Thanks Grant.

Maybe you are right.

Feel free to answer any questions that you feel you know the answer to. As for posting equations using Latex, please use google to search for instruction on how to do this.
