9) R is the region bounded by the curves ? = x^3 , y=2x+4 , And
the y-axis.
a) Find the area of the region.
b) Set up the integral you would use to find the volume of a
solid that has R as the base and square cross sections
perpendicular to the x-axis.
Let R be the two-dimensional region in the first quadrant of the
xy- plane bounded by the lines y = x and y = 3x, and by the
hyperbolas xy = 1 and xy = 3. Let (x,y) = g(u,v) be the
two-dimensional transformation of the first quadrant defined by x =
u/v, y = v.
a) Compute the inverse transformation g−1.
b) Draw the region R in the xy-plane and the region g−1(R) in
the uv-plane
c) Use the...
let R be the region bounded by the line y=0, by the upper part
of the circle x2+y2=4, and by the upper part
of the circle x2+y2=9. Find the circulation
of the force F= ( 5cosx-y3)i+ (x3+ 4x+
5siny)j around the curve C , where C is the boundary curve of the
region R , oriented counterclockwise. Draw the region R precisely,
and show the orientation of the curve C by putting arrows on C
let R be a region bounded by x = 0 and x =1 and y = 0 and y = 1.
Suppose the density is given by 1/y+1.Notice that R is denser
near the x axis. As a result we might
expect the centre of mass to be below the geometric
center(1/2,1/2). Also since the density does not depend on x we do
expect moment of inertia about the x axis to be 1/2. verify the
moment of inertia about...
Consider the region R, which is bounded by the
curves y=3x and x=y(4−y).
(a) Set up, but DO NOT SOLVE, an integral to find the area of
the region RR.

the solid resulting from revolving the region RRaround the
xx-axis.
(c) Set up, but DO NOT SOLVE, an integral to find the volume of
