Gandalf the wizard was walking down the street when a violent wind blew off his hat! His hat is the surface S
pictured below, and has parametrization 7 (u, v) = ((1 – u'/3) cos(v) – 4u², (1 – u'/³) sin(v), 5u) where
0 <u<1 and 0 <v < 27. The hat is oriented so that the normal vectors point outward. If the vector field F with
F = (2 sin(z?) + x, x cos () + y,ysin(e
*")),
is such that curl(F) describes the wind velocity, find the flux of the wind through Gandalf's hat. That is, find
curl(F) - ds.
dS.
z
V
Hint: Look at the grid curves of the hat to help determine the boundary. You can also try plotting in math3d!
