WebThis is the reduced row echelon form of our matrix, I'll write it in bold, of our matrix A right there. You know it's in reduced row echelon form because all of your leading 1's in each row-- so what are my leading 1's in each row? I have this 1 and I have that 1. They're the only non-zero entry in their columns. These are called the pivot entries. WebIf the matrix is the zero matrix, then all of the variables are free (there are no pivots). (b) True. Page 138 says that “if A is invertible, its reduced row echelon form is the identity matrix R = I”. Thus, every column has a pivot, so there are no free variables. (c) True. There are n variables altogether (free and pivot variables). (d) True.
