Key Concepts

Definite Integration

This concept involves calculating the area under a curve over a specific interval. It underpins the idea of accumulating a sum of infinitely small quantities, which is expressed as the limit of Riemann sums.

Numerical Integration

Numerical integration refers to a collection of methods used to approximate the value of definite integrals when it might be difficult or impossible to evaluate them exactly. These methods allow for estimation of the integral using discretized data or function evaluations.

Riemann Sum

A Riemann sum is a way to approximate the area under a curve by dividing the interval into several subintervals and summing over products of function values and subinterval lengths. It is the foundation for many numerical integration techniques.

Midpoint Rule

The midpoint rule is a specific numerical integration method where the function is evaluated at the center of each subinterval. This value is then multiplied by the width of the subintervals and summed to provide an approximation of the total integral, often yielding better accuracy than other simple Riemann sum approaches.

Partitioning of Intervals

This concept involves dividing the overall interval of integration into smaller, equally or unequally spaced subintervals. This division is crucial in numerical methods as it allows the application of techniques like the midpoint rule on manageable segments, improving the approximation of the integral.
