The present book is primarily intended for the use of students of Class XII who have opted for Applied Mathematics (Code 241) as an Academic Elective introduced by the Central Board of School Education for the session 2021 – 22 and onwards. The salient features of this book are : lThe subject has been developed in a systematic, logical and concise form to meet the requirements of all types of students. lThe exercises have been very carefully selected and properly graded so that the easier problems appear in the beginning and the difficult ones at the end of each exercise. lA good number of illustrative examples have been worked out before every exercise. These solved examples will help the students in tackling the unsolved ones. lHints have been provided, wherever necessary, in case of difficult questions. lLooking at the importance of diagrams and figures, they have been neatly and correctly drawn in such a way that the students can have the complete idea of the problems by simply looking at them. lAs per the latest question paper design, Very Short Answer Objective Type Questions have been included in each chapter. lSpecial efforts have been made in making the subject matter thoroughly exhaustive and nothing of important has been omitted.
