Mastering Equations: Tips for Writing Mathematical Expressions with Tex

[mikie1]

How does one do that? I did a seach an no luck. Its the function where one can draw intergrals and sumations.

It's not completely clear what you mean.

I suspect you are referring to the "special symbols" such as

"& int ;" ∫ or "& theta ;" θ . Notice that those symbols start with & and end with ; I put the spaces in so the code itself would show up.

You might also want to try "Tex", its more elaborate and information about it is given at

Also, when people type with the Tex, you can click on it and see how they wrote it...that works very well for learning how to write it, see examples of it...when I first learned it, I would go around the forums in search of post with Tex written in them and look at how they were done.
