WebIf E is of type III, then ET is also of type III; so det ET =1 =det E by Theorem 3.1.2. Hence, det ET =det E for every elementary matrix E. Now let A be any square matrix. If A is not invertible, then neither is AT; so det AT =0 =det A by Theorem 3.2.2. On the other hand, if A is invertible, then A =Ek···E2E1, where the Ei are elementary inchcape klaipedaWebDetermine ‘a’ so that 2a+1, a^2+a+1 and 3a^2-3a+3 are consecutive terms of an A.P.#AP#CBSE #Mathematics#ArithmeticProgressions #FirstTerm #CommonDifference... inappropriate elf on a shelf photosWebExample 1: For the given matrix below compute both det (A) and det (2A).
