Joint --- Introduction ---

This module is an exercise on the continuity and differentiability of real functions.

The server generates a function f of one real variable, containing parameters a 1, a 2,..., hich is defined by different formulas on two segments of an interval. Your aim is to find values for these parameters a i such that f is continuous and differentiable to a required order.

One can solve the problem either by a Taylor expansion, or by successive derivations. In the difficult cases, the resolution of a system of linear equations is also necessary.
