Publisher: BookBoon 2011
Number of pages: 122
Polynomials are the first class of functions that the student meets. Therefore, one may think that they are easy to handle. They are not in general! Topics as e.g. finding roots in a polynomial and the winding number are illustrated. Some of the topics only require an elementary knowledge of Calculus in one variable. Others rely heavily on Complex Functions Theory.

College students who wish to know something of the hyperbolic trigonometry, will find it presented in a simple and comprehensive way in the first half of the work. Readers are then introduced to the more general trigonometry of the complex plane.
