Course Materials

Textbook:  Elementary Linear algebra 6 ed. by Larson & Falvo

Text

Larson & Falvo, Elementary Linear algebra 6 ed.

This is an older edition. You should not need to pay more than $20 for it.

Objectives

(Refer to the syllabus)

Exams

2 Mid-term Exams and a Final Exam.

Discovery Labs

This course is partially based on discovery labs.

The main pedagogical principle is that students acquire knowledge through participating in group activities.

It is extremely crucial that you are not late for classes.

Discovery Labs

1. You can earn a maximum of 5 points for each discovery lab.

2. If you are late, the max. points you can get will be reduced according to the following rules:

......1-5 min. late ---> -2 points

......5-10 min, late -->-4 points

......>10 min.---------->-5 points

Class Participation

You can get class participation points by answering questions in class.

There are small group classwork almost everyday.

Class Participation

At the end of the quarter, your grades on class participation will be determined by the above activities and other observations by the instructor.

Class Participation

Please respect your instructor and classmates. Do not talk during the lecture. There will be

time for you to talk. Disruptive and disturbing behavior will not be

tolerated.

Class Participation

No text messaging, web surfing, email sending,……

Turn off your phone before you enter the classroom***.

Expectations - Handouts

You are expected to print and bring your handout to class unless…

you have a tablet that allow you display and write note on a electronic copy of the HO.

Fail to have your HO repeatedly will negatively impact your grade.

Expectations - Labs

Each group is expected to print and bring at least one lab to class unless…

you want to type your solutions and print it out.

One lab report per group. Due 5:50pm at the day of the lab.

Expectations - Solutions

Sufficient and precise solution steps are expected.

Do not skip steps. Pay attention to instructions given to you

in class, handout, and feedback from labs and homework.

Points Distribution

Exam 1 100 points

Exam 2 100 points

Final 60 points

Discovery Labs 60 points

Homework 70 points

Class Participation 10 points

Final Class Grade

90% A Range

80% B Range

70% C Range

60% D Range

Below 60% E

Missing Classes

You are responsible to catch up all the materials if you miss classes for whatever reasons (sickness, family issues, family Hawaii vacation, etc).

The instructor will not "re-teach" the lecture in any form including special appointments.

Make-Up Policies

If a student has a  documented conflict that will prevent him or her from taking an exam at the scheduled time, he/she must arrange IN ADVANCE with the instructor to take the exam early. 

Study Hints

Studying in groups is an efficient way to learn mathematics.

Pre-class Reading (2.5 hours)

ClassPost-class Study, homework

(6-8 hours) 

There are tutorials in the CD-ROM comes with the textbook.

Why Study Linear Algebra?

Why Study Linear Algebra?

Two most important math subjects that you can learn in college

Calculus, Linear Algebra

Technologically Speaking...

Calculus is (more or less) about “hardware”. Linear Algebra is (more or less) about “software”.

GPS (Not in Details)

Need 4 satellites. 4 measurements

of distance. Not accurate due

to “clock errors”. (Satellites have atomic clocks, but receivers do not!)

Therefore the “Pseudorange Equations”

For a moving vehicle, the coordinates need to be refresh very often.
