Student Guide:

The application of integration to Work is covered in Section 6.4. While the concept of Work is important in Physics, the main thing to get here is yet another example of taking a problem and turning it into an integral. The more examples like this you see, the more likely it will be that you think of trying this in your own work.

This is the week of Midterm #1. Typically, this midterm would go up to and include Section 6.3 of the text. Depending on the quarter and instructor, the material covered on the first midterm will vary. Ask your instructor for precise information on the sections covered. Keep these comments in mind as you look over old midterms in the archive. The midterm will probably be given in TA section on Thursday. Many instructors devote one lecture period to an in-class review session, the day before the midterm.

The remaining lecture day this week is devoted to Section 6.5, Average Value of a Function. You should try to get geometric insight into what this topic is about. Can you draw a picture that explains what the Average Value of a particular function is?

The short worksheet Astroid.pdf is intended to be given Tuesday, before the midterm. It provides a review of computing volumes of solids of revolution. It also introduces the astroid, a hypocycloid.
