This free course, Introduction to complex analysis, is an extract from the third level Open University course M337 Complex analysis, which develops the theory of functions of a complex variable, emphasising their geometric properties and indicating some applications.Introduction to complex analysis consists of two sessions. The first session covers differentiation, and the second session covers integration of complex functions. The course should take about 12 hours to study. This content forms part of the Dangoor Education collection, the educational arm of The Exilarch's Foundation.

    Having engaged deeply with this Introduction to Complex Analysis, the provided description proved entirely accurate, presenting a rigorous journey from the foundations of complex differentiation through to contour integration. The certificate of participation, received upon completion, accurately reflects the substantial intellectual investment, with the estimated time commitment mirroring the actual diligent study required. The progression to contour integration and the Fundamental Theorem of Calculus demystifies how path independence is not a given in the complex plane.
