You are the given the eigenvectors uj (a) Find the eigenvalues 1, 12 and As of the eigenvectors u1, u2 and us, respectively. A1 = -1 Correct answer, well done. 12 - -3 Incorrect answer. A3 = 4 Incorrect answer. (b) The vectors u1, u2 and us form a basis B of IR. Let v be the vector Find the coordinate vector [v] of v in the basis B. Correct answer, well done. (c) Calculate A20 v Below, you can use exponentials to enter your answer, you don't have to write the full decimal expansion of the entries of the vector below, which could be large numbers. For instance, to write 5 - 9" - 8, enter 5*9^(20)*8. 1-4^(21) 420 v -1-4^(21) 1-2*4^(21) Incorrect
