WebTherefore, given any one of these points, every -neighborhood of that point contains at least one point at which f is analytic, and the points z0 = 2; z1 = 1+i; z2 = 1 i; are singular points of f(z): Question 4. [p 78, #6] Use the results in Sec. 23 to verify that the function g(z) = lnr +i (r > 0; 0 < < 2ˇ) WebSingular point of a differential equation (in English usually critical point). A critical point of the differential equation. where P and Q are continuously differentiable functions, is a point at which the numerator and denominator of the right-hand side of the equation vanish simultaneously. Assuming the critical point to be located at the origin, we can use Taylor …
