This is a sequel to Mathematics for Engineers Volume 1 and 2. Like its predecessors, this book also contains a large number of solved examples for students to internalize concepts. With this provision, it is expected that aspiring engineers will not only be able to master the concepts, but also learn the techniques of solving different kinds of mathematical problems. As the book has gradually evolved from the lectures delivered by the authors and their colleagues over the years, they have been able to use their experiences to design in such a way that students are able to understand complex concepts and study with ease and minimum assistance from the teachers.
