Latex question:

  1. May 6, 2008 #1
    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}


    \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]
