Homework Equations
Simpson's Rule: (dx/3)* sum of(sequence of coefficients {1,4,2...2,4,1}*sequence of function values{f(0), f(1), f(2)...f(n-2),f(n-1), f(n)})
Volume using Shells: 2π ∫ (radius)(height) dx
Volume using Cross-Sections: π ∫ (outer radius)^2 - (inner radius)^2 dx
The Attempt at a Solution
I found the area (≈) under the curve using Simpson's law, how do i rotate it without a given f(x)? The book doesn't ask for the specific method (either shells or cross-sections), but I'd like to understand how to do both. Please help.
