find inverse of matrix
Answers
Step-by-step explanation:
The inverse of a square matrix , sometimes called a reciprocal matrix, is a matrix  such that

(1)
where  is the identity matrix. Courant and Hilbert (1989, p. 10) use the notation  to denote the inverse matrix.
A square matrix  has an inverse iff the determinant  (Lipschutz 1991, p. 45). The so-called invertible matrix theorem is major result in linear algebra which associates the existence of a matrix inverse with a number of other equivalent properties. A matrix possessing an inverse is called nonsingular, or invertible.
The matrix inverse of a square matrix  may be taken in the Wolfram Language using the function Inverse[m].
Step-by-step explanation:
To find the inverse of a 2×2 matrix swap: the position of a and d, put negative in front of being and c, and divide everything by the determinant. (ad-bc)
