Key Concepts

Trapezoidal Rule

The trapezoidal rule is a numerical method used to approximate the definite integral of a function. It works by dividing the area under the curve into a series of trapezoids, calculating the area of each trapezoid, and then summing these areas. This method is especially useful when an analytic solution is difficult to obtain or when working with discrete data points.

Subinterval Partitioning

When applying the trapezoidal rule, the interval over which the integral is defined is divided into a number of subintervals. The choice of the number of subintervals affects the approximation accuracy; more subintervals typically lead to a more accurate result. Each subinterval contributes to the overall approximation by providing endpoints at which the function is evaluated.

Definite Integration

Definite integration involves finding the exact area under the curve of a function between two endpoints. The process makes use of an antiderivative of the function and the Fundamental Theorem of Calculus, which states that the evaluation of the antiderivative at the boundary points gives the value of the definite integral.

Fundamental Theorem of Calculus

The Fundamental Theorem of Calculus connects the concept of differentiation and integration. It tells us that if a function has an antiderivative, then the definite integral over an interval can be computed by evaluating the antiderivative at the endpoints of the interval. This theorem provides the theoretical foundation for exact integration.
