Multivariable Calculus, MATH 241

Final Exam

Monday, May 11, 3:00 - 5:30 pm (Section 01)
Wednesday, May 13, 11:30 - 2:00 pm (Section 02)
Swords 328

The final exam is cumulative, that is, it covers all of the material from the first day of class onwards. Approximately 20 - 25% will cover material since the third midterm exam. This is Sections 13.1 - 13.4. It is recommended that you go over homework problems, class notes, the midterm exams, and the three labs. Many of the problems and questions we discuss in class are excellent examples of test questions. Some sample final exam questions are available here. The solutions to these questions are available here.

In addition, some review problems from the Chapter 13 Review Exercises are listed below. The odd answers are in the back of the book while the evens are listed here. The Concept Check problems at the end of each chapter (before the Exercises) are also a good source of questions. For problems from the earlier chapters see the previous Exam Review sheets. The final exam will be approximately twice the length of a midterm exam.

Note: You will be allowed a scientific calculator for the exam which does NOT have graphing capabilities. Please bring your own calculator. In addition, you will be allowed one "cheat sheet" 8.5 x 11 piece of paper, front and back, full of whatever formulas, graphs, etc. you wish. Creating this reference paper will be an excellent opportunity to review topics for the exam.

Exam Review Session: Sunday, May 10, 6:30 - 8:00 pm in O'Neil 112. Please come prepared with specific questions.

Chapter 13 Review, p. 975-976
Problems:   1a, 4, 6, 7, 9, 11, 13, 14, 15, 16, 17

The answers to the evens are:
4.   0 (what type of vector field is F?)
6.   e - 9/70
14.   Don't worry about showing that F is conservative. You can assume it is. The value of the line integral is 2 using the Fundamental Theorem of Line Integrals.
16.   3.
