Hour Exam 3 will be a 90-minute, self-timed, take-home, closed book exam.

For Hour Exam 3, you'll be allowed to use one single side of a standard sheet of note paper to help you remember the formulas and techniques you might need for the exam.

Here are some ideas about what to put on your sheet of notes.

• General formulas for volumes of surfaces of revolution, such as
  • Washers: volume = pi x ( (outer radius)² - (inner radius)²) x thickness
  • Shells: volume = 2 pi x radius x height x thickness
• The formula for the area of a surface of revolution (pp. 583-584)
• The absolute value theorem for sequences (Theorem 5, p. 730)
• The geometric sequence theorem (Theorem 7, p. 733)
• The definition of partial sums (Definition 2, p. 739)
• The geometric series theorem (Theorem 4, p. 740)
• The divergence test (Boxes 6 and 7, p. 743)
• The integral test (p. 749)
• The p-series test (Box 1, p. 750)
• The basic comparison theorem (p. 756)
• The limit comparison theorem (p. 757)
• The alternating series test (p. 761)
• The alternating series estimation theorem (p. 763)
