Given a 2x3 matrix A, find AA'.
A = mat[4 0 7; 9 -3 8].
See attachment for a cleaner version of the problem.
So, first let's determine A'. We simply interchange rows and columns, ...
A step-by-step solution is provided. The student is walked through the process of multiplying A by A transpose. The first step is determining A transpose, given the matrix A. Word Doc is attached.
