Solids of Revolution   Message List  
Reply | Forward Message #608 of 1655 |
Has anyone tried to graph the classic surface of Revolution problems from
Calculus using
GC? It seems like one should be able to see the region in the x-y plane, and
animate the
revolution to see the solid of revolution.

I can see the region by graphing:

x=(0 if y<((f(x) if y > g(x)) if a<x<b)

But I can't seem to get the revolution working. Any help would be appreciated.
