The Fourier transform and Fourier's law of conduction are also named in his honour. Fourier is also gener…
Fourier originally defined the Fourier series for real -valued functions of real arguments, and used the sine and cosine functions in the decomposition. Many other Fourier-related transforms have since been defined, extending his initial idea to many applications and birthing an area of mathematics called … Ver mais A Fourier series is an expansion of a periodic function into a sum of trigonometric functions. The Fourier series is an example of a trigonometric series, but not all trigonometric series are Fourier series.
