Unformatted text preview: 3 a The following fact gives properties of matrix product, Theorem 1.2 . Let A,B,C be three matrices and r be a scalar, we have A ( BC ) = ( AB ) C, r ( AB ) = A ( rB ) (associativity) A ( B + C ) = AB + AC (distributivity) Notice, in general AB 6 = BA , that is for most of the times, AB is not equal to BA. Using the matrix notation and matrix product, we can write the following system of equations ax 1 + bx 2 = y 1 cx 1 + dx 2 = y 2...
