(a) (5 points) Write out the 6th order Taylor approximation to f(x) = cos(x) centered at a = 0. (b) (5 points) Write out the remainder term for the Taylor approximation in part (a). (c) (10 points) Explain why in general, the remainder term for the n-th order Taylor approximation to cos(x) centered at 0 has absolute value less than or equal to |z|n+1 (n+1)! (d) (5 points) Use (c) to argue the radius of convergence of the Taylor series for f(x) = cos(x) centered at a 0 is infinite.
