5.72. Let A = A(0,1) and let g: A → be an analytic function sat- isfying 9(0) = 0 and 1g'(0) = 1 whose derivative is a bounded function in A. Show that w > (4m)-1 for every point w of C ~ g(A), where m = sup{]g'(x): z E A}; i.e., show that the range of g contains the disk A(0,(4m)–?). (Hint. Fix w belonging to C ~ g(A). Then w # 0. The function h defined by h(z)...

Q1. Show analytically that the Root Locus for the unity feedback system with open loop transfer function: (a) [10 marks] K(s 4) (s + 2) is a circle, and find the centre and the radius. Determine the minimum value of the damping ratio and the corresponding value of K (b) The root locus of the open loop transfer function: [10 marks] s(s26s +15) is depicted in Figure Q1(b). Find the minimum value of gain K that will render the system...
55. Show that a monotone function on an open interval is continuous if and only if its image is an interval. 56. Let f be a real-valued function defined on R. Show that the set of points at which f is continuous is a Gs set.

12.4. The Bessel function (of the first kind of order ser is defined by Jo(+) 2 (nl) This function is of considerable importance in applied mathematics, with merous applications to problems involving cylindrical containers, such as temperature distribution in a se pipe (6) Write out the partial num for the Bessel function of order sero up to the terms. If you have access to a graphing calculator or computer, use the graph of this partial sum to approximate, to one...
Problem 5. (20pts) The open-loop transfer function of a unity feedback system G(8) -- +2) a) Locate open-loop zeros and open-loop poles. b) Construct the root-locus diagram as 0 <K <oo. Mark the portions of the real axis that belong to the root locus - Mark with K =0 the point where the root locus bra O the point where the root locus branches start and with K = oo the point where the branches end. - Find break-away and/or...
Problem (3) A function f(z) is analytic in the disk -1 where the modulus satisfies the bound Here b 2 a > 0 Find an optimal bound on |f'(0) in terms of a and b. Complete arguments required By optimal it is meant that (1) the bound holds for all functions with the stated property and (2) there actually is a function with the stated property such that the bound holds as an equality. The second part of this problem...
Q5. a) Let f(z) be an analytic function on a connected open set D.
