PREFACE
The book has been written to provide a good concept about Ordinary Differential Equation to the students with the material in a systematic and easy-to-understand way. Before studying Differential Equations students should gather a good concept about mapping
or functions. Students are requested to know about domain, co-domain, open set, sequence,
convergence etc. If a student feels difficult to understand any portion, at this time it is our request
to the students, please don't waste time and immediately see corresponding examples. Then try to connect previous portion with example. A good number of examples have been given after every theory portion to understand easily. This is the first edition of this book. So, there may be many misprints. All are requested to
inform any misprint or any difficulty at sayansaha1990@gmail.com
We would like to thank all our students specially Pritam Chakraborty, friends specially Dr. Bikash Chakraborty and Colleagues specially Dr. Bijoy Bera for their help and support. We are also thankful to our family members specially Monami Pal. Finally, we express our sincere gratitude to the 'Techno World Publisher' for their interest and the patient co-operation in publication of this book.
Criticism and suggestions for the improvement of the book will be highly appreciated.
