• Holomorphic Functions and the Cauchy-Riemann Equations: Why Complex Differentiability Is So StrongComplex differentiability asks for one limit from every direction. We derive the Cauchy-Riemann equations, show partial derivatives alone fail, and prove exp, sin and Log holomorphic.MathematicsComplex AnalysisUndergraduateComplex analysisHolomorphic functionsCauchy-Riemann equationsTotal differentiabilityHarmonic functions~21 min
