1. The problem statement, all variables and given/known data Find the nth power of the matrix A, |1 1| |0 0| 2. Relevant equations 3. The attempt at a solution My guess is the A^n = PD^nP^-1 formula. But my prof says not use to eigenvalues and eigenvectors. Is it possible to solve this without using the formula A^n = PD^nP^-1 ???
