Builds on the content taught in Course - Metric Spaces MT23^U and generalises the study of real analysis in Prelims (Course - Analysis MT22^U, Course - Analysis II HT23^U and Course - Analysis III TT23^U) to the complex numbers, which turns out to be simpler than real analysis (sort of).
Proves some remarkable theorems related to functions which are complex differentiable:
