“Mathematical Methods for Economic Analysis” is designed to meet the requirements of a wide range of students, keeping in view the varied applications of mathematical techniques in different areas of Economics, Commerce, Finance, and Management, at the Undergraduate and Post Graduate levels. The subject matter has been presented in a very simple and lucid manner. A large number of questions from various University examination papers have been included to provide a range of questions on different topics of the subjects. Exercises given at the end of each topic will provide a source of practice to the students and make them more confident, assuring better performance in the Examination. Teachers in the subject may also find it absorbing and different from other books, in respect of approach, style, and lucidity in explanation supported by appropriate diagrams. One of its strongest features is that it emphasizes the unifying structure of economic theory in such a way as to provide the reader with the technical tools and methodological approaches necessary for undertaking original research. This book consists of 8 chapters such as Chapter-1: SET Theory, Chapter-2: The Number system, Chapter-3: Relations and Functions, Chapter-4: Limit and Continuity of a Function, Chapter-5: Derivative of a Function, Chapter-6: Partial and Total Derivatives, Chapter-7: Algebra of Matrix, Chapter-8: Determinants.
