Download the worksheet as a *.sws file.  This is just a zip archive.
Unpack it (possibly by renaming it first to have a .zip suffix).
You'll find a "data" subdirectory in there that should have the file
you want.

OR, open the worksheet in the notebook and look at the four drop-down
boxes right under the title.  The third one over says "Data..." - you
might be able to grab the file this way (and stuff it back into some
other notebook you are building similarly).

The "DATA+" construct is the notebook's way of letting you access this
file within commands in the worksheet.

This does everything I want:

However, the line

load DATA+"illustrate_numerical_integration.sage"

is problematic because I don't know where this file is.

I really like the @interact called "Numerical integrals with various
techniques" by Nick Alexander, which is located here:

http://wiki.sagemath.org/interact/calculus?highlight=%28simpson%29

However, I'd like to add Simpson's Rule to it. I see that Jason Grout
has an @interact with Simpson's, but it doesn't seem to work for me.
I was hoping that I might be able to copy the relevant code from
Jason's @interact and add it to Nick's, but I couldn't seem to figure
that out.  Any tips?  I'm definitely not proficient at making these
things, but usually have some success modifying them.

I'm curious if anyone has code for an @interact for Simpson's Rule that I could borrow. I checked out the interact wiki page, but didn't see one.

Thanks in advance.
