Attempt 1: The answer is incorrect. 4 attempts remaining. Use the Lagrange Error Bound to give a good bound for the error in approximationg cos(1.2) using an nth degree Taylor polynomial about z = 0. (Your answer should involve n. ) (1.2) 2n+2 A (272 + 2) ! Hint: since you weren't given a specific value for n, you can't directly compute the appropriate derivative. So how are you supposed to choose M? Even if you don't know the actual derivative, you can still say an awful lot about it. What's the maximum value it could possibly take? Try again Next item
