MATH 200-Section 103-Fall 2014

 

Instructor:
Instructor: Khoa D. Nguyen
Email: dknguyen at math.ubc.ca (or khoanguyen2511 at gmail.com)
Office hours: 5pm-6pm WTh at LSK 300C; or by email appointment.

 

Very important information:
- Course outline is here. Please read it very carefully.
- The
common page for all sections is here. It is password protected (read the course outline to learn how to access it). Please visit it regularly.

- Check the section “Announcements” below regularly.

- How to get the most out of the lectures: read ahead 1-2 sections before and review the notes after every lecture will help enormously.

 

Other useful information:
- Seek help early (instructors’ office hours, friends, Math Learning Centre,…), try not to fall behind since the material is cumulative.

- Do your best to minimize disruption during lectures.

 

Announcements:
Announcements, notes, practice questions, solutions,… will be posted below.

· Sep 3: access WeBWorK assignments here. First assignment due on Friday Sep 12 at 5:00pm.

· Sep 3: If you have a legitimate academic time conflict with the midterms, please email me asap with the following information: 1)Your name and student id; 2)Course number of the course that conflicts with the midterms.

· Sep 9: a new section called “Notes (that are not too useful)” is added below.

· Sep 17: small mistake in today lecture that could cause a wrong answer in WeBWorK. About definition of the angle between two planes I gave this morning, correction as follows. Correct definition: the angle between two planes is the ACUTE angle between the normal vectors (I did not mention “ACUTE” this morning). For the corresponding example: find cosine of the angle between two normal vectors using dot product, then find arccos like we did. EXTRA step:
         1) If that arccos is less than pi/2 (in radian), it is your desired angle between two planes.
         2) If that arccos is GREATER or EQUAL pi/2 (in radian), your answer is:
pi - that arccos
Alternatively (and perhaps better): find cosine of the angle between two normal vectors using dot product, then take the absolute value of that cosine, then take arccos of the resulting absolute value.

· Sep 21: midterm information is posted on the common page. This includes: seating plan (based on your last name), a lot of practice questions   (you should try as many as you can). Note that 14.3 is included; one way to prepare this is to work on WeBWork problems (even though they are due after the exam).

· Sep 21: review for midterm 1 on Friday September 26 from 4:05pm-4:50pm at IBLC 182.

· Sep 26: David Roe (another instructor of Math 200) will teach our class next week. Next week, my office hours are cancelled; but feel free to visit David’s office hours Tu 11:30-1:30 MATHX 1101; Th 1-3 MATHX 1102. If you have questions: talk to David or email me.

· Sep 26: a student asked an interesting question; I make it an extra example in page 4 of the note Sep26.pdf below.

· Sep 26: the marker in IBLC was too bad and my writing was barely visible. I upload the guide used in the review below.

· Oct 7: Your 1st midterm is returned today. Before asking questions, please read this first.

· Oct 27: read this for more details about rescheduled office hours and stuff about integrals.

 

Notes (that are not too useful):

A couple of students said it would be helpful to upload notes here. I am not quite sure about this (read disclaimer below); anyway here they are.

Disclaimer: these are the handwritten notes intended for me when preparing lectures. These notes might look messy, contain questions without answers, and answers without explanation (these extra details are given in the lectures). Using these notes without going to lectures could actually do more harm than good.
