- Verify the following functions f(z) are analytic for all z = x+iy. Use the Cauchy-Riemann conditions (Hint: find a way to express these functions as f(z) = u(x, y) + iv(x, y)). (a) f(2)=e* (b) f(2)=sin(z)proveA function f : A->R is given to be differentiable. A is an open interval. Let a1 and a2 (a1 < a2) are two real no. in A s.t. f'(a1 ) is not equal to f'(a2). If a0 is any no. between f'(a1) and f'(a2) then (i) prove that there exist some x0 in (a1 ,a2 ) s.t. f'(x0)=a0. (ii) Can we conclude that f' is necessary continuous on interval A. Note: This is complete question, no info missing..concepts which may be used to solve this question: formal definitions of continuity of a function and differentiability of a function, Intermediate value theorem.
- Let f: C→C be the function defined by ƒ(z) = izz. (c) Write f in the form f(x + iy) u{(2,y)+iz(x,y) where u, v : R² → R, and verify that the Cauchy-Riemann equations are satisfied if and only if x = y = 0.5. Theorem 4.27 says that if ƒ : [a, b] → R is Riemann integrable then ƒ² : [a, b] → R is Riemann integrable. Does the converse hold? Explain your answer.Don't give handwritten answer
- Show that a function f(x) = ∑ ∞n=2 (1/x-nπ + 1/nπ) is well defined on [0, π]. That is, prove the domain of the function f contains the interval [0, π].1. Consider the function f defined on [0, 0), 1 x" sin=, x # 0 f(x) = x = 0 where r > 0. Determine the range of r in which (a) f is continuous on [0, c0), (b) f is differentiable on [0,0), (c) f' exists and is differentiable on [0, 0).Suppose that the function f: R → R has the property that -x2 <ƒ(x)Let C = sin dx. As f(x) = sin(1/x) is continuous except at 0 and bounded, ƒ is integrable on [-1, 1]. Since the integrand is positive (never negative), C > 0. Put u = varibles to u so that f(x) = sin(u)² and dx = -u-2du. When x = u = -1. Therefore, 1/x and make the change of = 1, u = 1 and when x = -1, ´sin(u) = = - sin(u) (u-2)du C = du < 0. и Where does this argument go wrong?Question 4: For an m x n matrix A, show that m ||4||1 Elail = max 1Recommended textbooks for youAdvanced Engineering MathematicsAdvanced MathISBN:9780470458365Author:Erwin KreyszigPublisher:Wiley, John & Sons, IncorporatedNumerical Methods for EngineersAdvanced MathISBN:9780073397924Author:Steven C.
