This book is designed for first year engineering students of all branches and B.sc students. The explanation of topics will help the students easily understand the basic concepts. The tutorial approach followed in the text will enable students develop a logical perspective to solving problems. The aim of this book is to give a self contained introduction to the field of ordinary differential equations with emphasis on the dynamical systems point of view while still keeping an eye on classical tools as pointed out before.

Sequence and series may be considered to be the study of change and has widespread applications in fields of engineering , science and economics. The subject of Sequence and series is extremely pedagogical in nature and designed for the first year entrants to engineering and B,sc students. The examples and presentation help students to develop a comfort with the subject area and thereby understanding concepts become easy.
