Hello, please help me with this problem. Thank you for your help.
y = 2 cos(x), and the interval is [−4.01, 4.01].
(a) What is the error when using midpoints with 10 subintervals? (Do not round your answer.)
(b) What is the ratio of the left-endpoint approximation error to the midpoint error? (Round your answer to two decimal places.)
Thank you very much.
