...referred to as Cain’s notes), that I served as a primary text for an undergraduate level course in complex analysis. Throughout these notes I will make occasional references to results stated in these notes. The aim of my notes is to provide a few examples of applications of the residue theorem. The main goal is to illustrate how this theorem can be used to evaluate various types of integrals of real valued functions of real variable. Following Sec. 10.1 of Cain’s notes, let us recall that if C is a simple, closed contour and f is analytic within the region bounded by C except for finitely many points z0 , z1 , . . . , zk then k f (z)dz = 2πi C j=0 Resz=zj f (z), where Resz=a f (z) is the residue of f at a. 2 2.1 Evaluation of Real-Valued Integrals. Definite integrals involving trigonometric functions 2π We begin by briefly discussing integrals of the form F (sin at, cos bt)dt. 0 (1) Our method is easily adaptable for integrals over a different range, for example between 0 and π or between ±π. Given the form of an integrand in (1) one can reasonably hope that the integral results from the usual parameterization of the unit circle z = eit , 0 ≤ t ≤ 2π. So, let’s try z = eit . Then (see Sec. 3.3 of Cain’s notes), cos bt = z b + 1/z b eibt + e−ibt = , 2 2 sin at = eiat − e−iat z a − 1/z a = . 2i 2i Moreover, dz = ieit dt, so that dt = Putting all of this into (1) yields 2π dz . iz F (sin at, cos bt)dt...

...nteThe Integral Approach® Courtesy of The Integral Institute® "Integral" means "inclusive, balanced, comprehensive." The Integral approach may be contrasted to other methods—mythic, rational-scientific, pluralistic—which, as they themselves announce, exclude other approaches as being inferior. They are thus, by definition, partial and incomplete. These latter methods, although widely accepted and dominant in the world's cultures, tend to generate partial analysis and incomplete solutions to problems. As such, they appear less efficient, less effective, and less balanced than the Integral approach. Like any truly fundamental advance, the Integral approach initially seems complicated but eventually is understood to be quite simple and even straightforward. It's like using a word processor: at first it is hard to learn, but eventually it becomes incredibly simple to use. The easiest way to understand the Integral approach is to remember that it was created by a cross-cultural comparison of most of the known forms of human inquiry. The result was a type of comprehensive map of human capacities. After this map was created (by looking at all the available research and evidence), it was discovered that this integral map had five major aspects to it. By learning to use these five major aspects, any thinker can fairly easily adopt a more comprehensive, effective, and integrally informed approach to specific problems and their solutions—from psychology to ecology, from business to politics...

...Calculus is the mathematical study of change,[1] in the same way that geometry is the study of shape and algebra is the study of operations and their application to solving equations. It has two major branches, differential calculus (concerning rates of change and slopes of curves), and integral calculus (concerning accumulation of quantities and the areas under and between curves); these two branches are related to each other by the fundamental theorem of calculus. Both branches make use of the fundamental notions of convergence of infinite sequences and infinite series to a well-defined limit. Generally considered to have been founded in the 17th century by Isaac Newton and Gottfried Leibniz, today calculus has widespread uses in science, engineering and economics and can solve many problems that algebra alone cannot.

...3 Contour integrals and Cauchy’s Theorem 3.1 Line integrals of complex functions Our goal here will be to discuss integration of complex functions f (z) = u + iv, with particular regard to analytic functions. Of course, one way to think of integration is as antidifferentiation. But there is also the definite integral. For a function f (x) of a real variable x, we have the integral b f (x) dx. In case f (x) = u(x) + iv(x) is a complex-valued function of a a real variable x, the definite integral is the complex number obtained by b integrating the real and imaginary parts of f (x) separately, i.e. b b u(x) dx + i a f (x) dx = a v(x) dx. For vector fields F = (P, Q) in the plane we have a the line integral P dx+Q dy, where C is an oriented curve. In case P and C Q are complex-valued, in which case we call P dx + Q dy a complex 1-form, we again define the line integral by integrating the real and imaginary parts separately. Next we recall the basics of line integrals in the plane: 1. The vector field F = (P, Q) is a gradient vector field g, which we can write in terms of 1-forms as P dx + Q dy = dg, if and only if C P dx+Q dy only depends on the endpoints of C, equivalently if and only if C P dx+Q dy = 0 for every closed curve C. If P dx+Q dy = dg, and C has endpoints z0 and z1 , then we have the formula dg = g(z1 ) − g(z0 ). P dx + Q dy = C C 2. If D is a plane region with oriented boundary ∂D = C, then P dx + Q dy = C D ∂Q ∂P − ∂x ∂y dxdy. 3. If D is a simply connected...

...work, we present an extremely efficient approach for a fast numerical evaluation of highly oscillatory spherical Bessel integrals occurring in the analytic expressions of the so-called molecular multi-center integrals over exponential type functions. The approach is based on the Slevinsky-Safouhi formulae for higher derivatives applied to spherical Bessel functions and on extrapolation methods combined with practical properties of sine and cosine functions. Recurrence relations are used for computing the approximations of the spherical Bessel integrals, allowing for a control of accuracy and the stability of the algorithm. The computer algebra system Maple was used in our development, mainly to prove the applicability of the extrapolation methods. Among molecular multi-center integrals, the three-center nuclear attraction and four-center two-electron Coulomb and exchange integrals are undoubtedly the most difficult ones to evaluate rapidly to a high pre-determined accuracy. These integrals are required for both density functional and ab initio calculations. Already for small molecules, many millions of them have to be computed. As the molecular system gets larger, the computation of these integrals becomes one of the most laborious and time consuming steps in molecular electronic structure calculation. Improvement of the computational methods of molecular integrals would be indispensable to a further development in computational studies of large molecular systems. Convergence properties...

...Probability, Mean and Median In the last section, we considered (probability) density functions. We went on to discuss their relationship with cumulative distribution functions. The goal of this section is to take a closer look at densities, introduce some common distributions and discuss the mean and median. Recall, we define probabilities as follows: Proportion of population for Area under the graph of p ( x ) between a and b which x is between a and b p( x)dx a b The cumulative distribution function gives the proportion of the population that has values below t. That is, t P (t ) p( x)dx Proportion of population having values of x below t When answering some questions involving probabilities, both the density function and the cumulative distribution can be used, as the next example illustrates. Example 1: Consider the graph of the function p(x). p x 0.2 0.1 2 4 6 8 10 x Figure 1: The graph of the function p(x) a. Explain why the function is a probability density function. b.
