Hmmmmmm...Well I guess my first question is how do I write the integral...Do I have to have some sort of program or...???

Anyway, lets say I have some kind of simple integral and there is dx in front of it. What is that dx there for.

Do you mean how to you notate it? The "dx" refers to the variable of integration. If you were in terms of y, you would write "dy".

An example: [tex]\int xdx[/tex] This is in terms of the variable x, so we notate that by writing dx.

If you are asking about how to put such equations on this forum, double click on any equation you are interested in and a window will open showing the Latex code.

Double click on:
[tex]\int xdx[/tex]

For more information on Latex, see the "sticky" in the "General Physics" thread.
