Give examples and elaborate on the applications of the topic. After reading your textbook, I want you to have a good understanding of the fundamentals of each chapter and show it to me. Please don’t copy & paste from your textbook or some other online source. In other words, don’t plagiarize. You can read online material if it helps to understand the material, but you have to write your own sentences. Remember the university has a software to detect plagiarism.
