This paper contains a summary of the contents usually called Fourier Analysis.
Chapter 1 is dedicated to improper integrals and related convergence criteria.
The second one takes into the gamma and beta functions.
The third chapter examines the differential equations to partial derivatives.
The following chapters introduce the Fourier series, the orthogonal functions, the Fourier integrals and the Bessel and Legendre functions.
The last chapter introduces the Hermitte and Laguerre polynomials.
