Complex numbers are nowadays taught in precalculus courses all over the world. Their integration in the teaching of classical topics related to Calculus is truly illuminating in every sense. We illustrate this by giving applications of complex numbers to the topics of … where ω represents the angular frequency and the complex number z encodes the phase and amplitude as explained above. Improper integrals. In applied fields, complex numbers are often used to compute certain real-valued improper integrals, by means of complex-valued functions. Several methods exist to do this; see methods of contour integration.

Fourier transforms are a fundamental part of signal processing in electrical engineering and in order to properly understand, and employ Fourier transforms, one must have a background in complex analysis. In addition, some of the computation in circuit analysis involves complex numbers and phase shifts can be dealt with in the complex plane. 24/01/2017 · Video created as an assignment for a university subject.
