Aloha Jarmo,

I find it easiest to use separate sub-trees for the various different
documents I create from a given body of material.  In your case, I would
make a sub-tree for the book and a sub-tree for the handout.

If I try to create two different documents under the same heading, the
complexity overwhelms me.  Of course, you're writing a math book, so
your tolerance for complexity probably exceeds mine :)

Where possible, I #+name: the elements that will be used in more than
one place and then use #+call: lines to place them where I want.  

For figures, the source code blocks can be written to expose the
variables that let you set font size, etc., so the figures can look
different wherever they appear.

For other elements, the echo() function, which is part of the library of
babel, can be used.

** Echo function

#+name: test-list
  - One
  - Two
  - Three

#+name: test-table
| One   | Two |
| Three | Four |

#+name: echo-table
#+call: echo(input=test-table) :results table

#+results: echo-table
| One   | Two  |
| Three | Four |

#+name: echo-list
#+call: echo(input=test-list) :results list

#+results: echo-list
- One
- Two
- Three

I don't know off-hand the full list of elements that can be named and
echoed this way.
