1.2 - Row Reduction and Echelon Form Questions and Answers correct A rectangular matrix is in echelon form if it has the following three properties 1. All nonzero rows are above any rows of all zeros 2. Each leading entry of a row is in a column to the right of the leading entry in the row above it. 3. All entries in a column below a leading entry are zeros (Ex on pg 13) A matrix is in reduced row echelon form if... 1. All of the conditions for echelon form are true 2. Each leading...

Ch. 1.2 Row Reduction and Echelons Forms Questions and Answers correct Echelon form 1) All nonzero rows are above any rows of all zeros. 2) Each leading entry (left most nonzero entry) of a row is in a column to the right of the leading entry of the row above it. 3) All entries in a column below a leading entry are zero. Reduced echelon form 1) The leading entry in each nonzero row is 1. 2) Each leading 1 is the only nonzero entry in its column. Theorem 1: Uniqueness of the r...
