In the Wolfram Language a variable can not only stand for a value, but can also be used purely symbolically. In this post, we will derive the Green's function for the three-dimensional Laplacian in spherical coordinates. Green’s functions represent the scattering behaviour of a particular geometry and are required to propagate acoustic disturbances through complex geometries using integral methods. A function can always be reconstructed from its con-tinuous wavelet transform by means of the following resolu-tion of identity formula, provided that the wavelets are ad-missible [5], f C da a =-dxdy d < f a x y > a x y-¥ ¥-¥ z ¥ z ¥ z z y p 1 q y q y q 0 3 0 2, b, , , g b, , , g (20).
