i..................j...............k

d/dx...........d/dy..........d/dz

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.

Thanks very much

You forgot the little hats on the unit vectors.

Besides vmatrix you can also use pmatrix, bmatrix, or just matrix.

Code:

\begin{pmatrix}…

Code:

\begin{bmatrix}…

Code:

\begin{matrix}…

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
