I've forgotten a lot of it and am looking to relearning :). @P-F: Thanks for the note — I think the Jacobian, and linear algebra in general, would be great to cover.

Another topic that would be very interesting for you to cover is the Jacobian, which causes pain for many, many students (including myself). Thanks for the great explanation.

So if you are on a landscape given by z=cosy-cosx and u want to get from (0,0,0) to (4pi,0,0) by moving in the direction of the gradient in the positive x-direction how would u explain that? What would that path look like? Very good explanation by the way.
