Use the Trapezoidal Rule with n trapezoids to approximate the following integrals. R 1 sin(5x2. 0 1) dx, n = 5. R 17. ln(x + 2) dx, n = 5. R 2:1 pj cos xj dx, n = 3.
The exact answer for f x dx must be between 0.7811, the right Riemann sum, and 0.8675, 0. the trapezoidal rule. This is because the right Riemann sum will yield an underestimate whereas the left Riemann sum and the trapezoidal rule will yield overestimates.
Trapezoidal Rule Practice For each problem, approximate the area under the curve over the given interval using 4 trapezoids. 1) y = x + 6; [ 1, 5] 2) y = x + 4; [ −2, 2] For each problem, approximate the area under the curve over the given interval using 5 trapezoids. 3) y = −x2 − 2x + 9; [ −3, 2] 4) y = 2 x; [ 2, 7]
