11 11 Evaluate 6x dx using the trapezoidal rule and Simpson's rule. Determine The value of 6x dx is 336 (Round to the nearest tenth as needed.) i. the value of the integral directly. ii. the trapezoidal rule estimate for n = 4 11 iii. an upper bound for |ET| The trapezoidal rule estimate of 6x dx for n = 4 is] iv. the upper bound for ET as a percentage of the integral's true value. 3 v. the Simpson's rule estimate for n = 4. (Round to the nearest hundredth as needed.) vi. an upper bound for Es . vii. the upper bound for Es | as a percentage of the integral's true value. The upper bound of |ET | is (Simplify your answer.) ET as a percentage of the integral's true value is (Simplify your answer.) 11 The Simpson's rule estimate of 6x dx for n = 4 is. 3 (Round to the nearest hundredth as needed.) The upper bound of |Es| is (Simplify your answer.) Es as a percentage of the integral's true value is (Simplify your answer.)
