This course is offered to BTech 2nd/3rd year students. An introductory note, quiz, mid-semester and end-semester questions of last few years are provided here. In 2011 the NPTEL recorded 40 lectures, which can be viewed here. I have revised the content since then.Â
This site has few chapters of the book that I use as the main text.
