Find inverse of Matrix A using adjoint theorem. Write you answers in brackets " with space between entries, and use semicolon to separate rows from each other (for example [2 5; -1 1.5] demonstrates 2 5 -1 1.5 ). Use decimals if required. 2 0 0 A - 3 1 1 4 4 a) det (A) = [1 mark] b) co-factor matrix C - [3 mark] c) inv (A) - [2 mark]
