PREFACE
We thank the faculty and the students of various universities, Engineering colleges and others for sending their suggestions for improving this book. Based on their suggestions, we have made the follwoing changes. (i) New problems have been added and detailed solutions for many problems are given. (ii)C-programs of frequently used numerical methods are given in the Appendix. These programs are written in a simple form and are user friendly. Modifications to these programs can be made to suit individual requirements and also to make them robust. We look forward to more suggestions from the faculty and the students. We are thankful to New Age International Limited for bringing out this Second Edition.New Delhi M.K. Jain S.R.K. Iyengar R.K. Jain
