Description: This simulation shows the constant-width left, right, and mid-Reimann sum of several typical integrands. One can witness how the three methods work differently and also see the influence of the number of segments on the value of an integral.
Keywords: Integration, numerical integration, Reimann sum.
Learning Objectives: After successful completion of running the simulation with proper questions asked by the instructor, the student would be able to 1) graphically know the Reimann sum method of numerically integrating a function, 2) note the influence of the number of segments on the true error, 3) differentiate between the true errors obtained using the different types of Reimann sums.
Full Resources: The full resources for the topic include textbook content, PowerPoint presentations, multiple-choice tests, audiovisual lectures, and application examples.
Software Requirements: Latest versions of Safari, Microsoft Edge, Firefox, Google Chrome.
