The server generates a function f of one real variable, containing parameters a1, a2,..., hich is defined by different formulas on two segments of an interval. Your aim is to find values for these parameters ai 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.
