Course aims

This course aims to extend our understanding of differential and integral calculus from functions of a single real variable to functions of a complex variable. The differences between the two are often unexpected and very surprising. The theory of complex valued functions will give us many new insights into the real variable theory.

Course description

This is a first course in the theory and applications of complex functions, taught at the Higher level. Topics covered include analytic functions, Taylor and Laurent series, integrals, Cauchy's theorem, residues, evaluation of certain real integrals, Laplace transforms, conformal mappings and applications to differential equations.
