Publisher Summary This chapter discusses complex numbers. In rectangular form of complex number, every number expressible in the form x + yi, where x and y are real numbers and i =, is called a complex number. The complex number x - yi is called the conjugate of x + yi. In polar form, with each complex number is associated a magnitude and a direction.

In Part 1 of this programme on Complex Numbers, we discovered how to manipulate them in adding, subtracting, multiplying and dividing. We also finished Part 1 by seeing that a complex number a + jb can also be expressed in Polar Form, which is always of the form r(cos θ + j sin θ).

This first chapter has essentially an algebraic flavor. The exercises use elementary properties of the complex numbers. A first definition of the exponential function is given, and we also meet Blaschke factors. These will appear in a number of other places in the book, and are key players in more advanced courses on complex analysis. Almost no methods
