How To Calculate Determinant,Adjoint,and Inverse a 3X3 Matrix

Example Matrix :

1. Find Determinant:  The determinant will usually show up in the denominator of the inverse. If the determinant is zero, the matrix won't have an inverse.

2. Find Adjoint : M is referred to as minor.

3. Find the determinant of each of the 2x2 minor matrices.

4. Transpose to get Adjoint

5. Find Inverse With this Formula :

6. Calculate with The Formula Above and get the Inverse.
