    NOTE: University policy states that is your responsibility to check for scheduling conflicts with other final exams immediately. If you have a scheduling conflict please resolve it immediately per university policy here. However, if another instructor reschedules one of your final exams and causes a scheduling conflict, then it is that instructor's responsibility to resolve the conflict.

  3. Recall:   You should be recording your study times in your Study Journal daily.
    If you did not receive a "blue book" from me in which to keep your journal, let me know.

  4. Does anyone other than university students and university instructors use Maple?   (I do not receive compensation from MapleSoft.)
    See News Article 1 >>
    See News Article 2 >>

  5. I strongly encourage you to work with "study buddies."

  6. You should have all electronic devices (phones, i-whatevers, MP3 players, ear-buds, etc.) completely turned off and stowed before coming to class. Recording devices are strictly prohibited. Using electronic devices during class without my permission may result in their being confiscated and in academic discipline.

  7. If you miss a class, you should obtain copies of the lecture notes from a classmate.

  8. How much should a college student study?


  1. Review Problems. October 6

  2. Do all the examples in the first Maple tutorial entitled Basics. October 6
    1. Do not use the shortcut menu buttons in the left panel of Maple. Rather, manually type the commands as they appear in the Maple examples.
    2. You should work all assigned Maple examples immediately to help you prepare for the Maple assignments.
    3. There also may be Maple related questions on exams.

    Kettering has made Maple amply available on many PCs throughout the AB.

  3. Section 10.1 – Parametric Representations of Curves. October 8
    NOTE: I also posted examples there.

  4. Section 10.2 – Calculus with Parametric Curves. October 9
    I will finish this section on Friday, but you should do what you can asap.

  5. Do all the examples in the second Maple tutorial entitled Solutions of Equations. October 10
    You should complete Assignment 2 before doing this. Remember that these assignments will acquaint (or reacquaint) you with Maple and prepare you for the Maple assignments.

  6. Section 10.3 – Polar Coordinates. October 13

    Happy Columbus Day!

  7. Do all the examples in the second Maple tutorial entitled Solutions of Equations. October 16

  8. Section 10.4 – Areas in Polar Coordinates. October 17

  9. Section 12.1 – 3-D Cartesian (Rectangular) Coordinates. October 17

  10. Maple Assignment 1.    posted Oct. 19
    Due Monday, Oct. 27 at the beginning of class. Recall that late submissions are NOT accepted.
    You may work in groups of no more than 3 people. Collaboration of people from different groups will be treated as cheating. Make sure each member in the group learns from the assignment.

  11. Section 12.2 – Vectors in 2-D and 3-D Cartesian (Rectangular) Coordinates. October 22



  12. Section 12.3 – Dot Product & Projections. October 24

  13. Section 12.4 – Cross Product. October 27

  14. Section 12.5 – Lines & Planes. October 29

    I've added these two documents summarizing the vector products and their properties:

  15. Section 10.5 – Conic Sections. October 31

  16. Section 12.6 – Cylinders & Quadric Surfaces. November 5

    Only 5 students (17%) worked Opportunity 2 correctly. Remember that there will be a problem like it on Exam 2! I urge you to make passing each Opportunity a VERY HIGH priority! Remember that if you pass the Opportunity, you will have fewer problems to work on the exam!



  17. Section 14.1 – Functions of Several Variables. November 10    (covered on Friday)

  18. Section 14.3 – Partial Derivatives. November 12

  19. Supplemental Problems on Partial Derivatives. November 13

  20. Section 14.4 – Tangent Planes & Approximations. November 13

  21. Section 14.5 – Chain Rule. November 14

  22. Section 14.6 – Gradient & Directional Derivatives. November 17

  23. Maple Assignment 2 – Due at 10:15 on Wednesday, Nov. 26.   (posted Nov. 17)
    Follow these Maple Examples that you were to work with Assignment 17!

    Recall that late submissions are NOT accepted.
    You may work in groups of no more than 3 people. Collaboration of people from different groups will be treated as cheating. Make sure each member in the group learns from the assignment.



  24. Section 14.7 – Maxima & Minima (Local Extrema). November 24

  25. Read Section 15.1.   November 24

  26. Section 15.2 – Iterated Integrals. November 25

    BEWARE:    The math faculty have observed that during the final 3 to 4 weeks of a term, especially around and after Thanksgiving, many students have a tendency to: 1) skip class more, and 2) let their studies in math courses slide as they complete term projects or term papers in other courses. Be careful not to do that! I often see students leave entire pages blank on the final exam (indicating that they probably did not do the assigned homework), and they end up seriously hurt their course grade. Remember that the final exam is comprehensive and is worth 28% of the course grade, so make sure you continue to study and do all the assigned homework. Also, realize that one purpose of a final exam is so you can show that you have mastered a concept that you might have scored poorly on in one of the exams. So view the final exam as an opportunity to raise rather than lower your course grade.

Facie (noun)   \'fā • cē,    'fay • see\    pl. facies   \'fā • cēz,    'fay • seez\ :
  1. an image of one's face taken by oneself or by another person using a digital camera or phone,
    especially for posting on social networking sites or smartphones for personal identification.
  2. a photo ID showing only the face.
First Known Use of FACIE – 16:34 UTC, October 12, 2014 by Kevin G. TeBeest, Michigan USA
Formerly:   "profile photo" (archaic)
Usage:  Professor TeBeest sent a photo of himself playing his drums to his brother who wanted a photo ID for his smartphone. The brother whined saying, "Send me a photo of your ugly face you stupid. . .!" So Professor TeBeest sent his brother a facie.
Etymology:  French façade ("a false, superficial, or artificial appearance or effect," Merriam–Webster); Italian facciata, a derivative of faccia ("front"), from Latin facies ("face");
Geographical Use:  worldwide
Not to be confused with selfie, which is a photo taken by oneself of one's own body or part of the body, usually due to vanity.
The photo on your state driving license is an example of a facie.

Inform your friends and family! Let's make it go viral. Start using it in conversations and online and explain it when they ask you what it means. It's fun!


Remember that:

  1. You are responsible for successfully completing all assigned problems in all your courses.
  2. The exams may include problems similar to these assignments and lecture examples and may include questions about Maple.
  3. We must maintain a steady pace to cover the material that constitutes Math-203. If you have difficulty with a section, be sure to see me for help immediately.
  4. No matter how simple a topic appears when you see my examples or read the text, you will almost certainly have difficulty completing an exam if you do not practice the examples and do the assignments beforehand.
Tutors are available in the SARC (AB 3-341) and at various other places and times.
