Construct a`2xx3` matrix `A=[a_(i j)]` whose elements are given by `a_(i j)=(1-j)/(1+i)`

Text Solution

Verified by Experts

Given,`a_(i j)=(1-j)/(1+i)`
Rows=2 and columns =3
`a_(11)=(1-1)/(1+1)=0`,`a_(12)=(1-2)/(1+1)=-1/2`,`a_(13)=(1-3)/(1+1)=-1`
`a_(21)=(1-1)/(1+2)=0`,`a_(22)=(1-2)/(1+2)=-1/3`,`a_(23)=(1-3)/(1+2)=-2/3`
matrix=`[[0,-1/2,-1],[0,-1/3,-2/3]]`
