You must come up with the solid. Remember that the Jacobian determinant (u^2+v^2) must be used when transforming an integral to this coordinate system"
The function of the solid should be given in Cartesian coordinates, and please show the work done to convert to parabolic cylindrical coordinates and to compute the actual integral. It should also include a graph of the solid.
This shows how to construct a triple integral for a solid for the given conditions.
