Math Help - Write down the 3x3 matrices.

1. Write down the 3x3 matrices.

The question is as follows:
Please write down the 3x3 matrices.

a) A=(min(i,j))
b) B=((-1)^(i+j))
c) C=(i/j)
d) D=(i^(j-1))

Thank you.

2. i,j denotes the entry in the ith row and jth column of the matrix. Let's do 1 for an example:

$
[A]_{i,j}=\min(i,j)\Rightarrow A=\begin{pmatrix}
\min(1,1)&\min(1,2)&\min(1,3)\\
\min(2,1)&\min(2,2)&\min(2,3)\\
\min(3,1)&\min(3,2)&\min(3,3)\\
\end{pmatrix}=\begin{pmatrix}
1&1&1\\
1&2&2\\
1&2&3\\
\end{pmatrix}
$

Can you do the others now?

3. Thanks

That helped thank you. I also wasn't sure what the "min" operator was although that should have been obvious. I understand now. Thank you for your help.
