Main Question or Discussion Point

I'm new to physicsforums, so my math typing is limited to the standard keystrokes. 1/x!, 2x^2. d/dx ln(3^(x+7)), for example. SO how do I do the nice summation symbols, imaginary number i, derivative operator, etc.?


Thanks!


PS to admins: Sorry if this is in the wrong place, I wasn't sure where I should put it.

Use "LaTex" which is really a typesetting program that converts "text" into math symbols. On this particular board, you start with [ tex ] and end with [ \tex ] (without the space which I had to put in so they would show.
[ tex ]\frac{d e^{3x}}{dx}= 3e^{3x}[ /tex ]
without the spaces gives
[tex]\frac{d e^{3x}}{dx}= 3e^{3x}[/tex]

There is a tutorial on LaTex at the top of the thread list at

The Latex code to each formula is revealed in a small window when placing the cursor on the formula.
