Right inverse implies left inverse and vice versa Garth Isaak
Notes for Math 242, Linear Algebra, Lehigh University fall 2008

These notes review results related to showing that if a square matrix A has a right inverse
then it has a left inverse and vice versa. We begin by reviewing the result from the text
that for square matrices A we have that A is nonsingular if and only if Ax = b has a unique
solution for all b.

Nonsingular if and only if unique solutions

Left inverse if and only if right inverse
