This module is an exercise on the continuity and differentiability of real functions.
The server generates a function f of one real variable x, containing parameters a1, a2,..., which is defined by different formulas on three segments of an interval. Your aim is to find values for these parameters ai such that f is continuous (or continuous and differentiable, following the level of difficulty you have chosen).
One can solve the problem either by Taylor expansions, or by successive derivations. In the difficult cases, the resolution of a system of linear equations is also necessary.The most recent version
