Using LaTeX

[prodos]

Feel free to practice using LaTeX in this section of the TEWLIP forum.

For logged-in users, this section is not moderated, but it will get cleared regularly.

I'll be adding more information, but for now ....

If you already know LaTeX code, all you need to do is enclose it in "tex" tags:

Code: Select all

[tex] [/tex]


For instance, this:

Code: Select all

[tex] e=m c^2 [/tex]

... renders as this:
[tex]e=m c^2[/tex]

This:

Code: Select all

[tex]\sum_i \hat{\psi_i} cos(\alpha_i \pm \omega t)[/tex]

... renders as this:
[tex]\sum_i \hat{\psi_i} cos(\alpha_i \pm \omega t)[/tex]

To practice using LaTeX you can use these online LaTeX editors

[tex]i\hbar\frac{\partial}{\partial t} \Psi(\texbf{r},\,t) = \hat H \Psi(\texbf{r},\,t)[/tex]

[tex]i\hbar\frac{\partial}{\partial t} \Psi(\texbf{r},\,t) = -\frac{\hbar^2}{2m}\nabla^2\Psi(\texbf{r},\,t) + V(\texbf{r})\Psi(\texbf{r},\,t)[/tex]

[tex]\Psi(\texbf{r},\,t)[/tex]

[tex]\Psi(\texbf{r_1,...,r_n},\,t)[/tex]

[tex]i\hbar\frac{\partial}{\partial t} \Psi(\texbf{r_1,r_2},\,t) = \hat H \Psi(\texbf{r_1,r_2},\,t)[/tex]

[tex]F^{\alpha\beta} = \left(
\begin{matrix}
0 & -E_x & -E_y & -E_z \\
E_x & 0 & -B_z & B_y \\
E_y & B_z & 0 & -B_x \\
E_z & -B_y & B_x & 0
\end{matrix}
\right).[/tex]

[tex]J^{\alpha} = \, (c \rho, \vec{J} )[/tex]
