Estimate *7 cos(x) dx using the Trapezoidal Rule and the Midpoint Rule, each with n = 4. (Round your answers to six decimal places.) (a) the Trapezoidal Rule (b) the Midpoint Rule From a graph of the integrand, decide whether your answers are underestimates or overestimates. OT is an underestimate T4 is an overestimate M4 is an underestimate M4 is an overestimate What can you conclude about the true value of the integral? (Round your answers to six decimal places.) < 7 cos(x2) dx Use the trapezoidal rule, the midpoint rule, and Simpson's rule to approximate the given integral with the specified value of n. (Round your answers to six decimal places.) n=6 sinhvx)dx, n = 6 (a) the trapezoidal rule (b) the midpoint rule (c) Simpson's rule Use the trapezoidal rule, the midpoint rule, and Simpson's rule to approximate the given integral with the specified value of n. (Round your answers to six decimal places.) 2 L 7 ex + cos(x) dx, n = 6 (a) the trapezoidal rule (b) the midpoint rule (c) Simpson's rule Use the trapezoidal rule, the midpoint rule, and Simpson's rule to approximate the given integral with the specified value of n.
