There are many ways. Here's one:

The code is:

[tex]\left[ \begin{array}{ccc}

i & j & k \\

\frac{d}{dx} & \frac{d}{dy} & \frac{d}{dz} \\

x & y & z \end{array} \right][/tex]

If you do a search of these forums using the key words

latex matrix

I'm sure you'll find other ways. - Jun 9th 2009, 12:20 AMAmer

You forgot the little hats on the unit vectors. (Tongueout)

Hello, Amer!

You may want those small arrows to indicate vectors . . .

. . Use**\vec i**

If there are fractions in the matrix,

. . they may be too close together vertically.

[tex]\begin{pmatrix}

\frac{1}{2} & \frac{1}{3}\\

\frac{1}{4} & \frac{1}{5}

\end{pmatrix}[/tex]

. .

We can insert an extra vertical space with**\\[-4mm]**

[tex]\begin{pmatrix}

\frac{1}{2} & \frac{1}{3} \\ \\[-4mm]

\frac{1}{4} & \frac{1}{5}

\end{pmatrix}[/tex]

. .

Using**\\[-3mm]**results in a larger space
