Thus statement 1 is not always true when principal values are used in all three terms. Show that u x, y must be constant throughout the plane. To verify this corollary.

We now present a companion to Theorem 1. The question of predicting when contour integrals are independent of path or always have value zero when the path is closed will be taken up in Secs. Suppose that P z is not zero for any value of z. Our discussion is brief and does not include verification that equation 1 actually gives the inverse transform f t or describe conditions on F s that allow limit 5 to exist. Residues and Poles Chapter 7. Let two functions p and q be analytic at a point z 0. The book has always had two main objectives. In the w plane, integrate the Taylor series expansion see Example 1, Sec. Note that an antiderivative is, of necessity, an analytic function. Derive expression 11 in Sec. It can be useful in locating regions of the complex plane in which a given analytic function has zeros. Details of the verification are left to Exercise 7. He is coauthor with Dr. Suggestion: In part a , use the relations see Sec. Previous page.

While definition 2 provides a means of testing whether a given point w0 is a limit, it does not directly provide a method for determining that limit. Finally, since the derivative of a polynomial exists everywhere, it follows that every polynomial is an entire function. To prove the theorem, we introduce a polygonal path L 1 , consisting of a finite number of line segments joined end to end, to connect the outer contour C to the inner contour C1. Let f denote a function that is continuous on a simple closed contour C. The original integral 1 is, of course, simply a parametric form of integral 4 , in accordance with expression 2 , Sec. Note that an antiderivative is, of necessity, an analytic function. Previous page. A precise statement of this theorem is contained in the proof to follow. We let s denote the distance along L from the point P and let U denote the unit vector along L in the direction of increasing s see Fig. Make Money with Us. The second of transformations 2 is simply a reflection in the real axis. Verify a the associative law for addition of complex numbers, stated at the beginning of Sec. In order to prove this theorem, we first recall some important facts about line integrals arising in advanced calculus.
