1. One of the major topics of this course has been to solve the linear system Ax = b where A is an m x n matrix, and x and b are n x 1. (a) Describe the exact solution if A is n x n and is invertible. (b) If A is an m x n matrix where m > n, the system is usually inconsistent (the science word is "over-determined"). Write the equation that finds the best approximation to Ax = h
