PREFACE TO
THE REVISED EDITION:
It
gives me immense pleasure in presenting the thoroughly revised edition to my
esteemed readers. In the present edition entire text has been re-written in a
lucid manner without altering the basic structure and retaining the salient
features of earlier editions. Illustrative examples and Exercises given at the
end of every section/sub-section in each chapter have been arranged in the
increasing order of difficulty level and have been categorized into the
following categories:
BASIC-Based
on basic concepts and formulae
LOTS-Based
on lower order thinking skills
HOTS-Based
on higher order thinking skills
At
the end of each chapter Exercises consisting of large number of Fill in the
Blank Type Questions (FBQs) and Very Short Answer Type Questions (VSAQs) have
been given.
Some
salient features of this book are:
Detailed
theory with illustrations
Algorithmic
approach
Large
number of graded solved Examples
Large
number of FBQS, VSAQS
Large
number of graded Exercises
