Question

HELP PLEASE :)
Let R=(rij)24 with rij=i-j, find R

Answer 1

\[(x_{ij})_{24}, with
r _{ij}=i-j\]

Answer 2

its and r instead of the x

Answer 3

@jim_thompson5910 @SolomonZelman
any idea?

Answer 4

@Jhannybean

Answer 5

\[\large \sf R=(r_{ij})_{24} ~,~ r_{ij}= i-j\] @iambatman @wio help !

Answer 6

Hmm..... \[(i-j)_{24}\] I'm not quite sure how to solve these :\

Answer 7

Can we be more clear here about notation?

Answer 8

What does the \(24\) mean?

Answer 9

matrix dimension, 2x4

Answer 10

\[
R=\begin{bmatrix}
r_{1,1}&r_{1,2}&r_{1,3}&r_{1,4}\\
r_{2,1}&r_{2,2}&r_{2,3}&r_{2,4}
\end{bmatrix}=\begin{bmatrix}
1-1&1-2&1-3&1-4\\
2-1&2-2&2-3&2-4
\end{bmatrix}
\]

Answer 11

\[
R==\begin{bmatrix}
0&-1&-2&-3\\
1&0&-1&-2
\end{bmatrix}
\]

Answer 12

wait how did you get those number ?, not in the solution matrix, the previous one

Answer 13

oh i got it

Answer 14

\[
r_{ij} = i-j\implies r_{1,1} = 1-1
\]

Answer 15

thank you sooo much :)
