Abstract
I will make an assessment of all examples found out thanks to the
tool "locus of loci" and the other new tools of Cabri 2 Plus: Representation
of surfaces to find out maximums and minimums of functions of several
variables. Representations of simulations in statistics to find
out classical statistic theorems. Representations of the solutions
curves of differential equations and systems, to approach a new
teaching of this subject starting from experimentations.
