Part I: Complex Variables, Lecture 1: The Complex Numbers

## Part I: Complex Variables, Lecture 1: The Complex Numbers

Herb Gross explains the need to define complex numbers. He defines the structure of the system of complex numbers including addition, subtraction, multiplication, division, powers and roots and shows that the system is closed under all these operations.

Part I: Complex Variables, Lecture 2: Functions of a Complex Variable

## Part I: Complex Variables, Lecture 2: Functions of a Complex Variable

Professor Herb Gross discusses functions of a complex variable, limits, derivatives and the Cauchy-Riemann conditions. Functions of a complex variable that are differentiable everywhere are called analytic functions.

Part I: Complex Variables, Lecture 5: Integrating Complex Functions

## Part I: Complex Variables, Lecture 5: Integrating Complex Functions

Herb Gross generalizes the definition of the integral of a real-valued function of a real variable to the integral of a complex-valued function of a complex variable and examines the ramifications of this generalization.
