TRUNCATION ERROR VS. ERROR BOUND FOR THE NUMERICAL INTEGRATION TRAPEZOIDAL RULE

AUIDENCE : TEQU 4006

In this video we explain how we can calculate the truncation error even without knowing the exact value of the integral. To do this, we do it through two examples, one where we know the value of N ( # of steps) and we compare the truncation error with the real value of the integral minus the value obtained through the trapezoid rule.

We also include a second example where we set the truncation error to determine the number of steps required to reach such precision.

Finally, the truncation error values ​​were compared to the bound error values. From my point of view, the use of truncation error makes more sense than the error bound.
