Compute the flux of the vector field
vec(F)=4x^(2)y^(2)zvec(k)
through the surface
S
which is the cone
\sqrt(x^(2)+y^(2))=z
, with
0<=z<=R
, oriented downward. (a) Parameterize the cone using cylindrical coordinates (write
\theta
as theta).
x(r,\theta )=
y(r,\theta )=?
z(r,\theta )=
with <=r<=
and _((
)
)<=\theta <=
(b) With this parameterization, what is
dvec(A)
?
dvec(A)=
(c) Find the flux of
vec(F)
through
S
. flux
