👉 The term "sphenoidal" refers to a specific type of mathematical function, which is defined by its characteristic properties and notations. It involves the use of sinusoids and their derivatives, particularly in the context of wavelets, signal processing, and other related fields. In mathematics, a sphenoidal function is a class of functions that are analytic in a certain region around a point, where it can be expressed as an infinite series with coefficients involving sines and cosines. These functions have
