MATH 200-Section 103-Fall 2016
MWF 11-12 at Math Annex 1100

 

I teach 2 sections of Math 200: section 103 and section 104. The pace, quizzes, and midterms will be different, you MUST take the quizzes and midterms given to your section. Make sure YOUR SECTION IS 103 when using this page. This page is still under construction, below information might be modified.

 

Instructor:
Instructor: Khoa D. Nguyen
Email: dknguyen at math.ubc.ca (or khoanguyen2511 at gmail.com)
Office hours (shared between 2 sections 103 and 104):
2:15-3:15 on Monday, 4:30-5:30 on Wednesday, and 5-6 on Thursday at LSK 300B, or quick 5-minute questions after lectures (if the room is not occupied).

 

Most important information:

· Common page for all sections (maintained by our Instructor-in-charge Prof. Albert Chau).

· Textbook: mainly use a primary textbook, and occasionally secondary textbook #1 and secondary textbook #2. These are free to download, visit the common page for more details.
In the previous semesters, we used Stewart’s book “Multivariable Calculus (7th edition) which is an excerpt of his bigger book “Calculus: Early Transcendentals”. It’s also useful if you have any of these Stewart’s books (from previous courses, friends, or somewhere on the internet).

· Grade components: homework using WeBWorK, 6 quizzes, one midterm, and one final. Visit the common page for more details.

· Only one midterm on Friday Oct 14. This midterm takes place at our normal meeting time and room. Different sections will have different midterms. At the end, the scores will be scaled to ensure fairness among all sections.

· Final exam: all sections do a common final exam. The exact date will be announced later.

 

Some tips:

· Do not hesitate to visit my office hours, other instructors’ office hours (see the common page), the Math Learning Centre,…

· I follow the textbook closely. You should skim through the topics before and review the notes after each lecture, spend time on WeBWorK, and solve the suggested problems (including past exams) given in the common page.

· Study with friends.

 

Homework:

Due at 5pm on Friday. You can ask WeBWorK questions in my office hours (but NOT by emails).

The first assignment is open on Friday Sep 9 and due on Friday Sep 16.

Link to weekly WeBWorK

 

Quizzes:
6 quizzes mostly on Fridays except the one on Wednesday Nov 9. You have around 10-15 minutes for each quiz. You MUST take the quizzes given in your section. Your lowest quiz score will be dropped (so having a bad day or missing a quiz without a “documented reason” will not hurt).

 

Quiz 1: Friday Sep 16. Cover the lectures on Sep 7-9. Questions are very similar to examples done in the filled notes Sep07 and Sep09. Solution

 

Quiz 2: Friday Sep 30. Cover the notes Sep12, Sep14, Sep16, Sep19, Sep21, and the note extra-week3 (posted on Friday 9/23). Skip “torque”. For this quiz (but NOT for the midterm and final), you can skip “work”, “angle between 2 planes” and “angle between a line and a plane” (discussed in the note Sep21). I will give you the formulas for: projection of u onto v, distance from a point to a line, distance between 2 skew lines, and distance from a point to a plane. Solution

 

No quiz on Fri Oct 14 (midterm)

 

Quiz 3: Friday Oct 28. Cover Multivariable Chain Rule (including formulas for implicit differentiation), Directional Derivative and Gradient Vectors (including tangent planes of level surfaces and tangent lines of level curves using gradient vectors). These are given in the notes Oct05, Oct07, Oct12, Oct17, and Oct19. You can skip Directional Tangent Lines (first 2 pages of the note Oct19). I will give you 3 formulas: (1) formulas for implicit differentiation (when z is implicit in x and y), (2) directional derivative as dot product of gradient and the unit direction vector, and (3) tangent planes of level surfaces. Solution

 

Quiz 4: Wednesday Nov 9 (since Fri Nov 11 is a holiday). Cover 3 types of optimization problems given in the notes Oct21, Oct24, Oct26, Oct28, and Oct31. I will not give you any formulas (so you should know the second derivative test, identify boundaries, set up and solve the system of equations coming from the method of Lagrange multipliers on your own). Solution

 

Quiz 5: Friday Nov 18. Cover iterated integrals and double integrals over general domains as given in the notes Oct31, Nov02, Nov04, Nov07, and Nov09 (skip stuff involving polar coordinates in Nov09). I will not give you any formulas; you should know on your own when to move vertical (respectively horizontal) lines and do dx (respectively dy) later. Solution

 

Quiz 6: Friday Nov 25. Cover double integrals using polar coordinates and applications as in the notes Nov09, Nov14, Nov16, and Nov18 (skip triple integrals). I will give you the formulas for mass, moments, and center of mass. Solution

 

Midterms, final, and past exams:

Notes and calculators are NOT allowed. Formula sheets will be provided in the midterm and final. Visit the common page for more details.

Past finals: http://www.math.ubc.ca/Ugrad/pastExams/

Some past midterms: in the past, we had 2 midterms each year. So the second midterms below (held in November) contain a lot of extra materials that will not appear in our midterm. For more past midterms, visit the common page.

2014-MT1 2014-MT2 (in Fall 2014, all sections have common midterms. Each midterm is 1.5 hours long and some questions are pretty hard)

2015-104-MT1 2015-104-MT2 2015-105-MT1 2015-105-MT2 (in Fall 2015, different sections have different exam)

We (should) use Chapter 13 of APEX and since it does not treat cylindrical and spherical coordinates, we (should) use Chapter 14 of secondary textbook #2 for those topics. Alternatively, we can use Chapter 15 of Stewart. Raw notes: Oct31 Nov02 Nov04. Filled notes: Oct31 Nov02 Nov04

An extra note on some integration techniques. I posted this for my sections last year (so you should ignore the words “written assignment” at the end of the first page) extra-week9

Sections 13.3, 13.4, and 13.6 of APEX. Alternatively, we can use Sections 15.4, 15.5 (only Mass, Moments, and Center of Mass), and 15.7 of Stewart. Raw notes: Nov14 Nov16 Nov18. Filled notes: Nov14 Nov16 Nov18

These topics correspond to Sections 15.4, 15.5, and 15.7 of Stewart’s book.

Raw notes: Nov21 Nov23 Nov25. Filled notes: Nov21 Nov23 Nov25

These topics correspond to Sections 15.7 and 15.8 of Stewart’s book. Highly recommended problems: posted below together with recommended problems for Week 13. Based on previous final exams, topics in Week 12 and Week 13 (triple integrals in Cartesian coordinates, cylindrical coordinates and spherical coordinates) constitute around 25% of the final.

 

Week 13: triple integrals in spherical coordinates, then review for the final depending on how much time we have. Use Secondary Textbook #2 (since APEX does not treat spherical coordinates). Alternatively, we can use Section 15.9 of Stewart. Raw notes: Nov28 Nov30 Dec02. Filled notes: Nov28 Nov30

 

Extra notes with solutions of problems suggested previously:

An extra note on differential calculus: extra-differential. Warning: most of these problems are hard and not very common. Don’t spend too much time on them before you have learned the basics.

An extra note on integral calculus: extra-integral. Unlike problems in the note extra-differential above, these are typical problems and you should know how to solve them.
