# Basic Mathematics for Economists, изд. 2

 Автор(ы): Rosser M. 06.10.2007 Год изд.: 2003 Издание: 2 Описание: Economics students will welcome the new edition of this excellent textbook. Given that many students come into economics courses without having studied mathematics for a number of years, this clearly written book will help to develop quantitative skills in even the least numerate student up to the required level for a general Economics or Business Studies course. All explanations of mathematical concepts are set out in the context of applications in economics. This new edition incorporates several new features, including new sections on: financial mathematics; continuous growth; matrix algebra.
