Over the years, a number of books have been written on the theory of functional equations. However, very little has been published which helps readers to solve functional equations in mathematics competitions and mathematical problem solving. This book fills that gap. The student who encounters a functional equation on a mathematics contest will need to investigate solutions to the equation by finding all solutions, or by showing that all solutions have a particular property.  The emphasis here will be on the development of those tools which are most useful in assigning a family of solutions to each functional equation in explicit form.weiterlesen
