Return to List of Lectures

Misc

Hour exam 1 is Friday (Feb. 28)

• Covers material through matrices (lessons 1 through 6, e.g., expressions, variables, vectors, scripts, plotting, matrices, etc.)
• In class, full class time
• 3 - 5 short-answer questions (e.g., write fragments of Matlab code, tell me what fragments of Matlab code do, etc; 10-15 minutes per answer)
• Open reference materials (book, notes, computer) but closed person
  • “Reference materials” include Matlab

Programming project 1

• 3D plotting
• Handout
• I hope to use programming projects in a study of how well the “flipped” teaching works, separate from regular grades.
  • Anonymous scoring against course learning outcomes by me, grading against assignment-specific criteria by TAs
  • Consent form

Questions?

Cross product?

• Vectors w/ 3 elements
• (x,y,z) × (u,v,w) = (yw - vz, uz - xw, xv - uy )
• v1 cross v2 is perpendicular to both

Quiz 3
