Question

construct a matrix [aij]2×2 where aij = i-3j.
​

Answer 1

Answer:

Construct a 2×2 matrix

A=[aij] whose elements aij are given by ∣∣∣∣∣23i−j∣∣∣∣∣

solution: Since it is a 2×2 matrix

It will here 2 rows & 2 columns

Let the matrix be A

A=[a11a21a12a22]

Given, aij=2∣3i−j∣

For a11;i=1,j=1

a11=2∣3×1−1∣=1

For a12,i=1,j=2

a12=2∣3×1−2∣=21

For a21, i=2,j=
