Problem 1: a) (1.5 marks )Find the approximation Tio (using the Trapezoidal rule) for edx. Find the actual error produced in using this method of approximation. b) (1.5 marks) Find the upper bound on the error term | Er| and compare this to the actual error you found in part a). c) (2 marks) How large do we need to choose n to guarantee the estimate of In for the integral in part a) is accurate to 0.00001? Round all answers in parts a), b) and c) to 8 decimal places
