$\left | \begin{matrix} i & j & k \\ 0 & 2 &-2 \\ 4 & -1 & 0 \end{matrix} \right |$

just seeing if vmatrix made a difference over matrix. Apparently not.

Are you having problems or just testing code?

There's always pmatrix:
$\begin{pmatrix} i & j & k \\ 0 & 2 &-2 \\ 4 & -1 & 0 \end{pmatrix}$
or bmatrix:
$\begin{bmatrix} i & j & k \\ 0 & 2 &-2 \\ 4 & -1 & 0 \end{bmatrix}$
or Bmatrix:
$\begin{Bmatrix} i & j & k \\ 0 & 2 &-2 \\ 4 & -1 & 0 \end{Bmatrix}$
or even smallmatrix (for which you must provide your own delimiters):
$\left( \begin{smallmatrix} i & j & k \\ 0 & 2 &-2 \\ 4 & -1 & 0 \end{smallmatrix} \right)$

Probably a simple question. When I type upper case letters in LaTex they (sometimes) change back to lower case. Can someone help?

I don't think I've had upper case letters change to lower case ... can you type out an example so one can use "quote" to look at your format?

I've had this happen before as well.
