Estimate the minimum number of subintervals to approximate the value of . (5t* + 6t) dt with an error of magnitude less than 10 * using a. the error estimate formula for the Trapezoidal Rule. b. the error estimate formula for Simpson's Rule. . . . The minimum number of subintervals using the Trapezoidal Rule is (Round up to the nearest whole number.) The minimum number of subintervals using Simpson's Rule is (Round up to the nearest even whole number.)
