Suppose the parametrized curve
C
:
(f(u),g(u))
is revolved about the
x
-axis, where
g(u)>0
for
a<=u<=b
. the distance along the axis of revolution and
g(u)
measures the distance from the axis of revolution. b. Find a parametrization for the surface obtained by revolving the curve
x=y^(2),y>=0
, about the
x
-axis. a. Take a cross-section of the graph for
A_(0)(f(u),g(u),0)
and
A=r(u,v)
on the yz-plane. Choose the correct graph below.
