Main Question or Discussion Point

I'm having some trouble with LaTex.

Here is the LaTex code:

\frac{1}{q_{2}} = \frac{A q_{1} + B}{C q_{1} + D}

And it should produce this:

[tex]\frac{1}{q_{2}} = \frac{A q_{1} + B}{C q_{1} + D}[/tex]

Here, it's produced just fine. But in TeXnicCenter, it produces this instead:

[tex]1\frac{}{q_{2} = \frac{A q_{1} + B}{C q_{1} + D}}[/tex]


What am I doing wrong?

Well, I figured it out, but I don't know why I should have to do this: I surrounded both fractions with \left. and \right. (the invisible boundaries) and it works fine now.

\left.\frac{1}{q_{2}\right.= \left.\frac{A q_{1} + B}{C q_{1} + D}\right.

[tex]\left.\frac{1}{q_{2}}\right.= \left.\frac{A q_{1} + B}{C q_{1} + D}\right.[/tex]

When you want to display math you should switch to math mode by enclosing the equations like the following:

\[
\frac{1}{q_2} = \frac{A q_{1} + B}{C q_{1} + D}
\]

OR

$$
\frac{1}{q_2} = \frac{A q_{1} + B}{C q_{1} + D}
$$

If you want have have math within a block of text, ie. in-line, use single $ ... $.

Tagging on here, as it appears the above question has been answered (and it seemed excessive to start a new thread).

How does one correctly display the Angstrom symbol with the A correctly positioned below the circle?

The standard approach gives me this: [tex]\AA[/tex]

I know there's a workaround that I've used before but can not recall.

Edit: Nevermind, got it: Mathring [tex]\mathring{A}[/tex]

[tex]10^{-10}\text{m}= 1 \mathring{\text{A}}[/tex]
