Cheg 258 - Lecture Notes - Feb. 11, 2000

Announcements

• The first hour exam for this course is on 3/1/00.

Class notes

The main points of the lecture were

• Degenerate Matrices

Goals:

• Identify and solve degenerate systems of equations.

Reading

• The class notes and Ch. 6 of Kahaner.

Questions of the Day:

• Why do linearly dependent modelling functions lead to degenerate matrices?
• Does the modelling problem y=a + b cos(2*pi*t) lead to degeneracy if measurements of y are taken at t=0,0.5,1,1.5? If t = 0,1,2,3?
