LaTeX support is back!

[Robert]

I have finished the LaTeX implementation and managed to save all the existing LaTeX code! I had to go into the database and manually modify 143 records. There are some differences from the original implementation:

1. The images no longer show a white background when viewed with Firefox and IE.
2. If you hover your mouse over the formula, the LaTeX code will show.
3. The images are created one time only. Any future formula that had previously been rendered will reuse this image. This is the same as before but you may not have noticed.
4. There were some security holes before. Not anymore.

Here are some LaTeX references if you're new to latex and would like to learn more:

1. The Not So Short Introduction to LaTeX
2. A Crash Course in LaTeX © MathMedics, LLC
3. LaTeX Symbol Reference

You can also view the original thread that introduced LaTeX to the forums here.

Let me know if you find any problems.

This is the matrix notation for imaginary unit



However, the 'amp;' should not appear at all.

[math]\left(\begin{array}{cc}0&-1 \\ 1&0\end{array}\right)[/math]

[AntonioLao]

[math] \begin{displaymath} \left( \begin{array}{cc}0 & -1 \\ 1 & 0 \end{array} \right) \end{displaymath} [/math]

The latex parsing should be working better now. Let me know if you see any other problems.

Let me see. Does work? Apparently it does now. It appears imperative to leave a single space between the square bracket tex wraps and the formula, term or statement, otherwise problems will develop. Also, it is probably a good idea to preview your work in a true environment before posting it if it is a complicated expression. I notice unpredictable results when making errors, such as a huge preview panel that extends far beyond the sides of the screen and a very large empty selection block that appears in the editing window where the wrong code is entered.

I could assume that the as printed is already stored in the database and that is why it is displaying properly. So then apparently the expression [math] e=mc^2 [/math] is not, since it doesn't. But is. I could be assuming the wrong thing. But why can't I display Einstein's famous equation?

Many thanks for this capability. Still I do need to restrain myself going overboard.

I have learned something today Robert,I always thought that Latex was a womans undergarment,that is
before today!Thank you for putting me in the picture?

kind regards michael.
