Vector addition, the complex plane (Argand diagram), and Riemann sphere projections (extended complex plane). Analytic Functions and the Cauchy-Riemann Equations
Unlike some modern textbooks, only selected problems have answers. Self-learners may get stuck without a solution manual (which is hard to find for this book).
Second Edition (2005) is the most prominent, published by PHI Learning . : Detailed exploration of Taylor and Laurent series
: Proof that bounded entire functions must be constant, leading directly to the Fundamental Theorem of Algebra. 4. Series Representations
: Covers convergence of sequences, Taylor series, and Laurent series for representing functions near singularities.
Kasana details the properties of analytic functions, using Cauchy-Riemann equations as a cornerstone for differentiability.
