Question

C ( 3 , 3) = [ cij] , tal que cij = 3i - 2j

Answer 1

C(1,1) C(1,2) C(1,3)
C(2,1) C(2,2) C(2,3)
C(3,1) C(3,2) C(3,3)

Cij = 3i - 2j
C(1,1) = 3.1 - 2.1 = 1
C(1,2) = 3.1 - 2.2 = -1
C(1,3) = 3.1 - 2.3 = -3
C(2,1) = 3.2 - 2.1 = 4
C(2,2) = 3.2 - 2.2 = 2
C(2,3) = 3.2 - 2.3 = 0
C(3, 1) = 3.3 - 2.1 = 7
C(3, 2) = 3.3 - 2.2 = 5
C(3, 3) = 3.3 - 2.3 = 3

1 -1 3
4 2 0
7 5 3
