To post math formulas in this forum, you can use the following method:
1/ Insert your
TeX code in this
LaTeX renderer and create an image of the formula.
2/ Either host the image and include it in your post, or write directly the LaTeX code in your post (allow for some hours before it appears).
Example:LaTeX code:
\bf
\int H(x,x')\psi(x')dx' = -\frac{\hbar^2}{2m}\frac{d^2}{dx^2}
\psi(x)+V(x)\psi(x)
