Posting math equations

[fred2028]

How do some people post math equations in those images that resemble actual formulae and not stuff like x^2?

Go the top of this web page. There is a pull down tab “Forum Help”
On that tab there are several references.
What looks the most professional is produced be LaTex.
The program TeXAide is a free down load.
If you use Equation Editor it will look familiar.
If you use MathType you do not need any thing more.
MathType will produce the LaTeX code.

OK I got Texaide, but when I write an equation (x^2) I copy and paste and get the following:

% MathType!MTEF!2!1!+-

x^2

O.K.
Start TeXAide. Go to the tab “Preferences”.
Click on “Translators”
Activate the ‘radio box’ “translate to other languages (text)”.
In the translator window select “TeX-LaTeX 2.09 or later”.
UnCheek any other boxes.
The click OK.

Now when you highlight and copy a formula you will get something like
\[
\left( {x - y} \right)^2 \ge 0 \Rightarrow \quad x^2 - 2xy + y^2 \ge 0 \Rightarrow \quad x^2 + y^2 \ge 2xy
\]
Change that to

 [tex] \left( {x - y} \right)^2  \ge 0 \Rightarrow \quad x^2  - 2xy + y^2  \ge 0 \Rightarrow \quad x^2  + y^2  \ge 2xy [/tex]

When you post it you will get.
\(\displaystyle \left( {x - y} \right)^2 \ge 0 \Rightarrow \quad x^2 - 2xy + y^2 \ge 0 \Rightarrow \quad x^2 + y^2 \ge 2xy\)

You can also type the code manually. For instance, I will do this just by typing the code:

\(\displaystyle \boxed{\lim_{x\to{0}}\frac{e^{x}-1}{x}=1}\)

OK in my program I had to go Edit > Translators. And there weren't any of the options you referred to, but the following was found:

I unchecked both checkboxes and here's what I got:

\[
x_2
