Solving real integrals with complex analysis
WebThis is known as the complex version of the Fundamental Theorem of Calculus . Theorem: Let f(z) = F ′ (z) be the derivative of a single-valued complex function F(z) defined on a domain Ω ⊂ C. Let C be any contour lying entirely in Ω with initial point z0 and final point z1. Then ∫Cf(z)dz = F(z) z1z0 = F(z1) − F(z0). WebMATH20142 Complex Analysis 8. Solutions to Part 1 8.
