The basic idea behind this form of the method is to: Equate the first sample moment about the origin M 1 = 1 n ∑ i = 1 n X i = X ¯ to the first theoretical moment E ( X). A special flavour of complex analysis arises because one may think of the C both algebraically as a number system and geometri-cally as a vector space. attending a meeting (Santa Barbara, 2015) on the revitalization of complex analysis in the curriculum. For an example of the insights that you gain using complex variables, consider the function f(x) = 1= 1 + x2. Using probability sampling methods. (If you run across some interesting ones, please let me know!) Let us now investigate another trick for solving Poisson's equation (actually it only solves Laplace's equation).
