Hi there, I just wandered in. I thought I had a fairly good idea of how to do #1, but I'm not too fond of the answer I keep finding. The problem in question is at the top of my scanned sheet dealing with work and line integral.

Note the vector field is conservative so g can only be a function of z so our function is by the fundemental theorem of line integrals we can just evaluate at the end points for the value. I hope this helps.
It sure did. Thanks a bunch.
