The Fourier series is named in honour of Jean-Baptiste Joseph Fourier (1768–1830), who made important contributions to the study of trigonometric series, after preliminary investigations by Leonhard Euler, Jean le Rond d'Alembert, and Daniel Bernoulli. (You can also hear it at Sound Beats.) \( f(x) = \left\{\begin{matrix} 0 & x \in [-1,0)\\ x+1 & x \in [0,1] \end{matrix}\right. 0. The SH transform works on the spherical surface. 2.
