Inverse of a Matrix by Gauss Jordan MethodThe inverse of an n n matrix A is an n n matrix B having theproperty thatAB BA I[A / I]RREF[I / A-1 ]B is called the inverse of A and is usually denoted by A-1 .If a square matrix has no zero rows in its Row Echelon form orReduced Row Echelon form then inverse of Matrix exists and itis said to be invertible or nonsingular Matrix.If Row Echelon form and Reduced Row Echelon form of Matrixpossess zero row then inverse of Matrix does not exist and theMatrix is said to be singular.One can solve System of Linear Equations AX B if Inverse ofA exists, which yields X A-1 B.

Inverse functions mc-TY-inverse-2009-1 An inverse function is a second function which undoes the work of the ο¬rst one. In this unit we describe two methods for ο¬nding inverse functions, and we also explain that the domain of a function may need to be restricted before an inverse function can exist.
