It is well known that mathematics is an essential tool for engineering and scientists. It provides material that can help people working in applied sciences. Generally, it widens the skills and abilities of humans for logical analysis, correct thinking in problems and therefore deciding the suitable decisions. This book "APPLIED MATHEMATICS for ENGINEERS" lies in six Chapters. In each Chapter the scientific material is given and illustrated in a simple method, covered with enough solved examples which are suitable for engineers as well as students who are interested in topics of this book. Moreover, at the end of each Chapter there are additional unsolved problems for training and applications. Finally, I hope to be offered a scientific service for engineers and students.
