Introduction to Engineering Mathematics-II

The book has been thoroughly revised according to the New Syllabaii of Gautam Buddha Technical University, Lucknow. Question papers of 2010, 2011 and 2012 have been solved & included at the end of textbook. The misprints which came to my knowledge, have been removed. The previous edition book had the text material for both First & Second Semesters. Now to make the book handy, we have bifurcated the book in two parts, Volume I and Volume II. Volume II of the book is for Second Semester Students.

(II SEMESTER)[For B.E./B.Tech./B.Arch. Students of Second Semester of all Engineering Colleges of Gautam Buddha Technical University, Lucknow]

The main features of the book are as follows:

1. Objective Type Questions.

2. Multiple Choice Questions.

3. Fill in the Blanks

4. True/Flase.

5. Matching Type (Total number of objective type questions are more than 600).

6. Additional Important Examples Question Papers of 2012 and 2013 have been solved and included in text. A number of new example are solved and included in the body of the text.
