Approximate the integral using
(a) The midpoint approximation $M_{10}$,
(b) The trapezoidal approximation $T_{10}$, and
(c) Simpson's rule approximation $S_{20}$.

Find the exact value of the integral and approximate the absolute error for each case. Express your final approximation answers to six decimal places.
