Easy trick | how to find inverse of a matrix

Explanation:

Easy trick to learn how to find inverse of any matrix using this simple method. 

Steps to follow:

1) First find determent of given matrix. 

for 2*2 and 3*3 matrix we will find separately. 

2) Now find adjoint of the given matrix. 

For 2*2 matrix 

Let us suppose, 

A=1      2

     3      4

Then it's determinant we would be

|A|=1*4-2*3=4-6=-2
