, Preface
It gives me great pleasure in presenting the new edition of this book. In this
edition, the modifications have been dictated by the changes in the CBSE
syllabus. The structure and the methods used in the previous editions, which
have been appreciated by teachers using the book in classroom conditions,
remain unchanged.
In this edition certain topics that are no longer a part of the CBSE syllabus
have been retained so that students do not face difficulty in competitive
examinations, etc. These topics include conditional identities involving the
angles of a triangle, infinite geometric series and exponential series.
The main consideration in writing the book was to present the considerable
requirements of the syllabus in as simple a manner as possible. Special
attention has been paid to the gradation of problems. This will help students
gain confidence in problem-solving.
One problem faced by students is the lack of a comprehensive and
carefully selected set of solved problems in textbooks of this kind. I have given
due weightage to this aspect. Each set of solved examples is followed by a
comprehensive exercise section in which students will get enough questions
for practice. Hints have been given to the more difficult questions. Students
should take their help as a last resort.
I have received many suggestions and letters of appreciation from teachers
all over the country. I thank them all for contributing in the improvement of
the book and for their encouragement. I hope they will like this edition as well.
And as always, I would like to hear their views on the book.
