basis is Consider the endomorphism f of R3 whose matrix in the canonical 1 1 +(#3) A = -20-2 5 1. Calculate the characteristic polynomial P; of f and the eigenvalues of f. 2. Prove that f is diagonalisable and find a basis of eigenvectors. 3. Check that Pf(f) = 0 and deduce the inverse of f. 4. For any n Z, calculate the matrix of f" in the canonical basis. basis is Consider the endomorphism f of R3 whose matrix in the canonical 1 1 +(#3) A = -20-2 5 1.
