Insert a new line in TeXShop

  1. I'm having the following problem in TeXShop - how can I put two equations in two separate lines?
    Thus far I have something like:

    Code (Text):
    \[
     p_y = s \cos \alpha \\
     p_x = s \sin \alpha
    \]
    But I still get the two on the same line..
    Help would be very much appreciated

  3. You need to use one of the multiline environments.
    The most basic of which is array (used inside \[\])
    The best is probably (as long as you're using the amsmath package)
    Code (Text):
    \begin{align}
     p_y &= s \cos \alpha \\
     p_x &= s \sin \alpha
    \end{align}
    where the ampersands (&) are alignment markers.
    This produces
    [tex]\begin{align}
    p_y &= s \cos \alpha \\
    p_x &= s \sin \alpha
    \end{align}[/tex]
