In this lesson, you will learn about numerical integration.
- Review the definition of a definite integral as a limit of Riemann Sums.
- Use appropriate technology to numerically estimate definite integrals using the midpoint, trapezoidal, and Simpson’s rules.
- Estimate errors involved in numeric integration.
