The quiz consists of a) 15 short answer and b) one written question. The quiz topics for the 15 short answer questions are listed below. Of these 15 questions, in general, the first seven questions are from the lecture notes, questions 8-11 are from the first readings discussion of this quiz period, and questions 12-15 are from the second readings discussion. The questions from the lecture notes will have one or two of the math problems covered in lecture.
The potential written questions are listed below.
Eight quiz questions will come from the readings discussion questions: four from the first readings discussion and four from the second readings discussion.
