Nettet5. mar. 2024 · To find the inverse of a matrix, we write a new extended matrix with the identity on the right. Then we completely row reduce, the resulting matrix on the right will be the inverse matrix. Example 2. 4. ( 2 − 1 1 − 1) First note that the determinant of this matrix is. − 2 + 1 = − 1. hence the inverse exists. NettetIn mathematics, the bounded inverse theorem (or inverse mapping theorem) is a result in the theory of bounded linear operators on Banach spaces.It states that a bijective bounded linear operator T from one Banach space to another has bounded inverse T −1.It is equivalent to both the open mapping theorem and the closed graph theorem.
