As per unified u.G.C. Syllabus for b.A./b.Sc.(general and honours) 1. The matter has been prepared in a simple and lucid language, so that students themselves shall be able to understand the solutions of the problems. 2. Each chapter opens with necessary definitions and complete proofs of the standard theorems and results. These in turn are followed by solved examples which have been classified in various types and methods. This classification will help the students to revise the subject matter at the time of examination without losing any confidence. 3. Care has been taken not to omit even a minor step so that the students can understand everything without the guidance of a teacher. Hence even an average student will be able to grasp the subject matter easily. Furthermore, the problems have been graded in every chapter to instill confidence in the students. 4. Up-to-date yearwise reference of various examination papers have been given throughout the book. 5. At the end of each chapter objective type questions have been given in keeping with the latest trend of question papers. 6. This book serves as a suitable textbook, help book, reference book and question bank for all examinations. Table of contents chapters 1. Basic concepts of dynamics 2.
