Find the second Taylor polynomial T2(x) for the function f(x) = cos(x) based at b = π6. T2(x) = Let a be a positive real number and let J be the closed interval [π6−a, π6+a]. Use the Quadratic Approximation Error Bound to verify that |f(x)−T2(x)| ≤ a33! for all x in J Use this error bound to find a value of a so that |f(x) − T2(x)| ≤ 0.01 for all x in J. (Round your answer to six decimal places. ) a =
