The Lebesgue Integral,e functions in Section 4.1, and in Section 4.2 prove two fundamental results on convergence of integrals: . and the .. We define the integral of extended real-valued and complex-valued functions in Section 4.3. . (those functions for which the integral of |.| is finite) are introduced in Section 4.4

The , Spaces,s of all essentially bounded functions on the domain ., was introduced in Section 3.3, and . which consists of the Lebesgue integrable functions on ., was defined in Section 4.4. Now we will consider an entire family of spaces . with

Hilbert Spaces and ,ne the angle between vectors, not just the distance between them. Once we have angles, we have a notion of orthogonality, and from this we can define orthogonal projections and orthonormal bases. This provides us with an extensive set of tools for analyzing .

Convolution and the Fourier Transform,s. Using this operation we will prove, for example, that the space . of infinitely differentiable, compactly supported functions is dense in . for all finite .. Then in Section 9.2 we introduce the ., which is the central operation of harmonic analysis for functions on the real line. In Section 9.3
