Approximate Integration: Example 3: Midpoint Rule

in #mathematics5 years ago (edited)

In this video I go over another example on approximate integration and this time use the Midpoint Rule with 10 sub-intervals to approximate the integral of the function ex2 from x = 0 to x = 1. In fact there is no exact integral solution of this function and thus approximations are the only way to evaluate the integral. In this example I also go over the upper error bound for the approximation to see how accurate our approximation is with the midpoint rule.

Approximate Integration: Example 3

Approximate Integration Example 3.jpeg

a) Use the Midpoint Rule with n = 10 to approximate the integral:

b) Give an upper bound for the error involved in this approximation.

Note:

  • Error estimates are upper bounds for the error.
  • They give theoretical, worst-case scenarios.
  • The actual error in this case turns out to be about 0.0023.
