WebDeterminants and inverses A matrix has an inverse exactly when its determinant is not equal to 0. ***** *** 2⇥2inverses Suppose that the determinant of the 2⇥2matrix ab cd … WebThe determinant is only used to find the inverse itself. However, finding the inverse is (as you found out first hand), pretty difficult and prone to error. So people have worked out ways of solving the same problem A*x=b using other methods, one of which is using what is called LU decomposition.
