Find a normal vector to the surface x y - z 2 = y 2 z - 1 at the point ( 7 , 3
Find a normal vector to the surface at the point Then find the equation of the tangent plane at this point.
Let be the region in the plane bound by the lines and Set up a single iterated double integral to compute using the order of integration or whichever one is appropriate Then compute the double integral using the function
Reverse the order of integration and evaluate the integral:
Consider the region bound the line the axis, and curve This is a "wedge" contained in the second quadrant. Write in setbuilder notation using polar coordinates:
Convert the following double integral from Cartesian to polar coordinates. Then evaluate the integral:
Consider the region in the plane bound by the curves and Let be the solid lying above the region and below the plane
a Use the appropriate double integral to compute the volume of the solid
b Use the appropriate triple integral to compute the volume of the solid
c Find the average value of the function over the region
Consider the solid below the paraboloid and above the plane. A cylindrical hole is cut through this solid using the cylinder resulting in a new solid Set up a double integral in polar coordinates for computing the volume of the solid then compute the volume.
Consider the solid bound by the sphere and the paraboloid in the first octant. Set up a triple integral in cylindrical coordinates to compute the volume of this solid.
Let be the top half of a ball of radius centered at the origin. Find the average distance of points in from the origin using the appropriate triple integral in spherical coordinates.
Hint: Set up a function which gives the distance of the point to the origin. Then use the triple integral formula for the average of a function.
