# Matrix Properites

### Matrices, Determinents, Methods

When will a Matix (A) NOT have an inverse? 0 in diagonal det(A) = 0 2 rows same or multiple (after Gaussina) Row of 0
What must be SQUARE? Matrices with Inverse Determints Upper/Lower Triangular Matrices Diagonal Matrices
Properties of Determint det(A T) = det (A) det(AB) = det(A) det(B) BUT det(A+B) NOT = to det (A)+det(B) Mulitply diagonal when Upper/Lower/Diagonal
det(A -1) = 1/det(A)
Methods to solve for Inverse [A|I n] to find [I n|A -1] A -1 = 1/det(A) x adj(A)
Properties of Matrix (A+B)C = AC+BC C(A+B) = CA+CB (A+B)T = A T = B T (AB) T = B T x A T (KA) T = KA T (A T)T = A
Methods to solve a Matrix Gaussin-Elimiation (work to Row-Echeln form) Cramer's Rule Multiply [A] -1 x [b]
