Fourier analysis, named after the French scientist Joseph Fourier, is the study of the way general functions may be represented or approximated by sums of simpler trigonometric functions; the transform is the breakdown or analysis of the functions. Fourier analysis has applications in physics, partial differential equations, number theory, combinatorics, signal processing, imaging, probability theory, statistics, option pricing, cryptography, numerical analysis, acoustics, oceanography, sonar, optics, diffraction, geometry, protein structure analysis and other areas.
