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]
The trapezoidal rule and the left and right Riemann sums were used to estimate f x dx , where f. is the function whose graph is shown below. The same number of subintervals were used to produce each approximation. The estimates were 0.7811, 0.8675, and 0.9543.

The following diagram shows the Trapezoid Rule to find an approximation to an integral between two limits. Scroll down the page for more examples and solutions on how to use the Trapezoid Rule.. Integration - The Trapezium Rule (C4 Maths A-Level Edexcel) Show Step-by-step Solutions. Trapezium Rule. Show Step-by-step Solutions.
Walk through an example using the trapezoid rule, then try a couple of practice problems on your own. By now you know that we can use Riemann sums to approximate the area under a function. Riemann sums use rectangles, which make for some pretty sloppy approximations.
