1first, compute the integral analytically. then estimate the integral to 6 decimal places, as instructed. a) handwork use multiple applications of the trapezoid rule, with n=6. (use eq. 19.11). b) handwork apply the composite trapezoid rule, with n=6. (use eq. 19.17). c) matlab apply the composite trapezoid rule, with n=6, 12 & 24 d) handwork use multiple applications of simpson’s 1/3 rule, with n=6. (use eq. 19.22). e) handwork apply the composite simpson’s 1/3 rule, with n=6. (use eq. 19.26). f) matlab apply the composite simpson’s 1/3 rule, with n= 6, 12 & 24
