Volume by Shells in Calculus

[Simon]

Hi libman,

"Kindof" is the best answer I can give you.  In Autograph you can either do a volume of revolution of the area under y = f(x) around y = k where you specify k OR you can do a volume of revolution about any straight line.  In the latter case the volume is not calculated.  

So to show a volume by shells (but not calculate it):

1. Plot y = f(x)
2. Select your curve > right-click > Find Area to find the area between two points
3. Plot x = 0
4. Select Slow Plot
5. Select the area and the line x = 0
6. Right-click > Find Volume...

Hope this helps,

Simon
