Compute det A, det B , and det(A + B ) for: A= 12 31 and B= det(A + B ) = det A + det B in general. 2 −1 42 Determinants and Inverses Outline Linearity of the Determinant Determinants and Invertibility Determinants and Products Scalar Multiplication with Determinants If k is a scalar, is it true that det(λA) = λ det A? Let k = 2 and take A as above. Determi...
