The purpose of this set of (mostly) short answers is to provide a way for students to check on their work. Our answers here leave out a lot of intermediate steps; we hope this will encourage students to work out the intermediate steps for themselves. We also have a set of longer and more detailed answers, which is available to instructors only from Cambridge University Press.
