The attached patch includes a new doctest for a book (in french) some people are writing about Sage, under the supervision of Paul Zimmermann.

This patch contains only the doctests for two chapters (about calculus and graphics and solutions for corresponding exercices).

This doctest was tested successfully with Sage 4.6.2 under Debian Squeeze.
