Euler’s Identity (Complex Numbers)

How the Fourier Transform Works, Lecture 4 | Euler’s Identity (Complex Numbers) Next Episode: Course playlist: In order to describe the Fourier Transform, we need a language. That language is the language of complex numbers. Complex numbers are a baffling subject but one that it is necessary to master if we are to properly understand how the Fourier Transform works. What is the imaginary number “i” and why it is so useful to us when dealing with the Fourier Transform? This is the sixth in this series of videos which takes a new and visual look at the maths behind the magic of how the Fourier Transform works.
