I am going to bed soon, but check out the page I put together on Lagrange Multipliers: https://sites.google.com/a/ctyonline.net/jdinoto/mvc/unit-2/lagrange Michael Corral's text has a NICE explanation with tons of examples. http://www.mecmath.net/calc3book.pdf Also this: http://synechism.org/drupal/cfsv/ is a SUPER reference, though it has a few largely trivial typos.
