The book is designed for undergraduate and graduate students in mathematics, physics, and engineering. It provides a comprehensive and rigorous treatment of complex variables theory, along with numerous examples and applications.
The culminated power of this theory lies in the . This theorem transforms difficult real integrals—often impossible to solve with standard calculus—into a simple algebraic sum of "residues" at the function's poles. Practical Applications of Kasana's Theory
Covers the extension of real numbers to complex systems, triangle inequalities, and polar/exponential forms.
