Question: Estimate an upper bound on the absolute error in approximating integral 0 to 2 of exp(-x 2 )dx by the composite trapezoid rule with 10

Estimate an upper bound on the absolute error in approximating integral 0 to 2 of exp(-x2)dx

by the composite trapezoid rule with 10 points. Show a plot to determine the maximum absolute value of the second derivative of the integrand in the range of integration. Assume the exact value is 0.882081.

Report the composite trapezoid rule result and its actual absolute error.
