L 3.1-3.3 -- Vectors and Coordinate Systems

Questions of the Day:

• How do you compute line, surface, and volume integrals in each coordinate system?

Reference Material:

• Textbook sections 3.1-3.3
• Lecture Notes: L15.pdf  Download L15.pdf 
  (We will not have time to cover all of the vector operations in class, so please review these notes and refer to Ch3 as needed during the following sections.)
• Also refer to your math and physics books.
• The Right Hand Rule Picture Book Right Hand Rule
•  A review of coordinate systems by Daniel Fleisch Links to an external site.
•  3D field models Links to an external site.

Video Lectures: (Watch videos 1,6,10-13,14,16 before coming to class):

I have done several review sections and examples of line, surface, and volume integrals in all 3 coordinate systems.  Please listen 1,6,10-13,14,16 before class.  The others you can leave for later reference as needed.

Applications:   You can’t believe your eyes!  Cell Phones and Popcorn:

Search YouTube for ‘cell phone popcorn’ for some really great EM amusement.  I especially like this one Links to an external site., because of the direction of the antennas (WHICH direction does power come out of an antenna???) And after you’ve seen a few of the eye poppers, check this one Links to an external site. out too.  And guess what?! Bananas can pop corn too Links to an external site.!
