2. For given integral I = || -dx: %3D a) Use Midpoint Rule and Trapezoidal Rules with n=6 to approximate the given integral I. b) Estimate the upper bound on the error in calculated M, and T 6. c) Find a value of n that ensures that M, approximates the given integral to within the specified degree of accuracy. The degree of accuracy is 0.0001

a) left endpoint = ? b) Right endpoint = ?
