Numerical Integration Methods: Apply It

  • Estimate definite integrals using the midpoint and trapezoidal rules
  • Use Simpson’s rule to find definite integrals with a specified accuracy

Approximating Integrals in the Real World

When exact antiderivatives aren’t available, scientists and engineers use numerical integration to approximate values. For example, when modeling curved surfaces, predicting population changes, or estimating travel distances, approximation methods like the midpoint rule, trapezoidal rule, and simpson’s rule give reliable results. Let’s practice these techniques.
