Re: Volume of a 3d figure
Look, Tommy Boy,
The first guy said:
<<Does anyone know how to find the volume of a 3d graph? Say you wanted to find
the volume of a walnut looking solid, how would you do this with the 89? I know
how to do this via integration and the like using pencil and paper, but I was
looking for a shortcut via the 89.>>
Then I said:
<<89s can do symbolic and numeric integration. Just numerically integrate Pi
F(x)^2 from A to B. Not that hard. For arc length, numerically integrate
sqrt(1+F ' (x)) from A to B.>>
That was a coherent reply that told him how to find the volume of a 3D solid.
Duuuh.
