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.
![Page 15: Log into your account](https://reader036.vdocuments.net/reader036/viewer/2022062516/56812c5b550346895d90e6ab/html5/thumbnails/15.jpg)
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.

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.

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?
![Page 32: Log into your account](https://reader036.vdocuments.net/reader036/viewer/2022062516/56812c5b550346895d90e6ab/html5/thumbnails/32.jpg)
Why Study Linear Algebra?
Two most important math subjects that you can learn in college
Calculus, Linear Algebra
![Page 33: Log into your account](https://reader036.vdocuments.net/reader036/viewer/2022062516/56812c5b550346895d90e6ab/html5/thumbnails/33.jpg)
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.
Need efficient ways to do this!
