Physical problems in fluid flow, electrostatics, and engineering mechanics. How to Study Complex Variables Effectively
. While real-valued functions map lines to lines, complex functions map two-dimensional regions to other two-dimensional regions. This shift opens up powerful tools for solving problems that are intractable using real calculus alone.
