Lesson: Numerical Integration: The Trapezoidal Rule Mathematics • Higher Education

In this lesson, we will learn how to approximate definite integrals using the trapezoidal rule and estimate the error when using it.

Lesson Plan

Students will be able to

understand the derivation of the formula used for the trapezoid rule,
approximate the area between a curve and the by dividing it into a given number of trapezoids and by using the formula,
identify whether an approximation using the trapezoidal rule is an overestimate or an underestimate,
calculate the percentage error when using the trapezoidal rule compared to the exact value of the integral.
