Hi,
I have a triple integral and i would like to plot it in Mathematica to understand the object and the implications of its volume under the curve.
It's easy to integrate and the answer is 57375 / 64.
The triple Integral is as follows:
? ? ? x^3 * y^5 * z dxdydz z = (1,2); y = (z, 4z); and x = (z/y, 2z/y)
I have done the following, most of the syntax i copied from another demonstration but i still think it is not the real shape of the object in question:
r = ImplicitRegion[{z > 0, y > 0, z >= 0}, {x, y, z}];
i = HoldForm[
Integrate[x^3*y^5*z, {z, 1, 2}, {y, z, 4*z}, {x, z/y, 2*z/y}]];
cp = ContourPlot3D[{z, y, z}, {x, 0, 40}, {y, 0, 40}, {z, 0, 40},
Mesh -> None, ContourStyle -> {Red, Green, Blue, Orange},
PlotLegends -> "Expressions"];
rp = RegionPlot3D[r, PlotPoints -> 100, Background -> Black];
TraditionalForm[
Column[{r, Row[{i, "=", ReleaseHold[i]}],
Row[{"Volume[r]= ", Volume[r]}], Row[{cp, rp}]},
Alignment -> Center]]
Can someone help me to plot the actual object in 3D?
Thanks
