First step find determinant of A. If det A not =0 then find co factor of A. Then find A transpose of co factors.then formila for A inverse = 1/Det A × A transpose C..

Best Engineer tutor having lots of results.

Because matrix is a arrangement of datas. So it has no solution. Inverse is another type of rearrangement

Normally we find the inverse of matrix in 2 ways... 1. using the formula -- Inverse of A = (1/|A|) Adj(A)... You can observer determinant of A i.e. |A| is an real number if it is equal to zero the inverse of matrix is will be undefined. So |A| must be non zero. 2. We can use elementary row transform...

We have 3 methods:- 1. Elementary row or column method 2. Finding AdjA /|A| 3. If we are given an equation in A then multiplying suitably both sides by A inverse. For demo online class take appointment.

when A=2,3,4,5,its inverse is first you put square matrix for this.then in that matrix first enter 2 and 3 as first row and 4 and 5 as second row. now you want to cross multiply( 1/)then you put square box then you change the position of first row first coloum with 2nd row 2nd coloum. then change...

Inverse of a matrix is defined only if |A| is not equal to 0. First find the minors and then co-factors. Minor of 'a'ij is the determinant of elements in rows and columns leaving row-i and column-j. Then find cofactor; cofactor of 'a'ij= (-M)^i+j Further find adjoint which is the transpose of the matrix...
