Question

Help me with a shortcut method of finding matrices using inverse method​

Answer 1

Answer:

There is no manual shortcut except you're using a program like MATLAB or Mathcad.

Otherwise the process still remains the same:

1. Find the determinant |a|

2. Find the minor, then find the cofactors C

3. Find the adjoint of a which is the transpose of C

4. Find the inverse with

$\frac{1}{ |a | } \: \times adjoint \: of \: a$
