6. a. Compute the integral of the friction (o o) for - 27 on the region bounded by the parabola y - (a f 1); and the line y - 5 - 1. b. Compute an approximate value of ( vibe da using the Midpoint rule, the Trape zoidal rule, and Simpson's rule. Start with " - 4 intervals, and double the number of intervals until two consecutive approximations are within 10 " of each other
