Announcements:

• The final exam is next Tuesday, June 6, at 8:30.
  • It is a cumulative, but it will focus on the later parts of the course (Taylor series and power series solutions to differential equations).
  • As with the other exams, it is closed book, no notes or calculators allowed. I'll provide some tables of information I think might be helpful--integrals and so on--just like on the second exam.
• Information about the first exam:
  • The median was 82 (87 after the revisions).
  • The average was 80 (84 after the revisions).
• Information about the second exam:
  • The median was 85 (86 after the revisions).
  • The average was 78 (81 after the revisions).

Homework:

• Do these before the final exam. Do not hand them in. Click here for solutions.
  • Section 5.2: 1, 2, 3, 4.
  • Section 5.3: 2, 3, 11, 12.
