The principal argument of the complex number −1−𝑖 is (a) 3𝜋 4 (b) −𝜋 4 (c) −3𝜋 4 (d) 𝜋 4 Each Complex Analysis problem is tagged down to the core, underlying concept that is being tested. The x-axis on a complex plane represents the real part of a complex number and the y-axis represents the imaginary part. The argument principle in complex analysis relates the difference between the number of zeros and the number of poles to the closed integral of the logarithmic derivative of an analytic function. Let's unravel the nuances of nodal analysis together. Also we claim if A;B2N, with A6= B, then ngis a sequence of bounded complex measurable functions on X, and f n!funiformly on X. 5 Absolute Value 1. Review of Complex Numbers.
