Question

construa a matriz aij= 3x3 4j^2-i^2

Answer 1

a11=4.1^2-1^2=4.1-1=4-1=3
a12=4.2^2-1^2=4.4-1=16-1=15
a13=4.3^2-1^2=4.9-1=36-1=35
a21=4.1^2-2^2=4.1-4=4-4=0
a22=4.2^-2^2=4.4-4=16-4=12
a23=4.3^2-2^2=4.9-4=36-4=32
a31=4.1^2-3^2=4.1-9=4-9=-5
a32=4.2^2-3^2=4.4-9=16-9=7
a33=4.3^2-3^2=4.9-9=36-9=27
