WebIn Section 3, we derive an explicit formula for Green’s functions in terms of Dirichlet eigenfunctions. In Section 4, we will consider some direct methods for deriving Green’s functions for paths. In Section 5, we consider a general form of Green’s function which can then be used to solve for Green’s functions for lattices. WebSo a function is like a machine, that takes a value of x and returns an output y.The set of all values that x can have is called the domain, and the set that contains every value that y can have is called the codomain.A function is often denoted by italic letters such as , , .. If this happens, then we say that y is a function of x, and we write = ().Here, is the name of the …
