The Fundamental Theorem of Calculus establishes a crucial connection between differentiation and integration. This section discusses the conditions under which a continuous function ( f ) on the interval ([a, b]) has an antiderivative ( F ) and offers insights into evaluating definite integrals. By recognizing that ( F ) can be used to determine the net signed area between the function graph and the ( x )-axis, this theorem simplifies the process of calculating integrals. Examples and practice problems enhance comprehension and application of these concepts.

The Definite Integral If a function f is continuous on an interval [a,b], then f is integrable on [a,b], and the net signed area A between the graph of f and the interval [a,b] is This is called the definite integral of f from a to b. The numbers a and b are called the lower limit of integration and the upper limit of integration, respectively.
