The institute (ICAR-CIFE) has continuously adopted itself to meet the current needs, methodological challenges, and quality enhancement in fisheries education with the advances in information technology. The increasing application of mathematics to various branches/courses of economics in the past decade has made it necessary for economists to have an elementary knowledge of mathematics. To this end, an attempt has been made to bring out a practical manual on mathematics for catering to needs of fisheries students, most of whom having a non-mathematical background during their tertiary education. This book has been structured to solve problems on a wide range of topics such as matrix, determinants, limit & continuity, differentiation, integration, partial differentiation, etc. It is hoped that the book brought out will serve as a useful source of knowledge to the students and also will help them in solving various types of mathematical problems.
