Day 33: Linear Algebra

Today:

• Don't forget: we've got an exam coming up Friday. The exam will go through 5.2 (one problem from 5.2 homework will appear on the exam). I'll post old exams by Wednesday. Earlier if harassed....

• Section 4.5 homework returned
  • Graded #1, 19

• Section 4.6 homework due

• Projects:
  • Second Project (you have until 4/25)
  • Again, you have a wiki link -- give it a try!

• Questions about old stuff?

• Current Business:
  • Let's finish up a few things:
    • 5.1: Eigenvalues and Eigenvectors
      • section 5.1 highlights (pdf)
      • Eigenvalue/vector applet with "lecture" -- worth checking out.
      • Check out the Fibonacci situation with this eigenvalue applet

    • How to find Eigenvalues and Eigenvectors
      • 5.2: The Characteristic Equation
      • Eigen examples:

  • Something new: section 5.3 highlights (pdf): Diagonalization
    • Example: #33, p. 326
