Hi, something that might work. There is a method of calculationg the volume of rotated curves, something= like 2*Pi*Intergal or so. It is not terribly sophisticated we had it in sch= ool. There is also a package, I think of Tom Wickham Jones: Mathematic Graphics= which will show the Surface of Revolution. It is available in MathSource.= and might help. =46abian ------------------------------------------------------------------------- Dipl.Biol.
