This module is an exercise on the infinitesimals (and its notation by O and/or o). The server generates a function $f(x)$ of one real variable $x$, containing parameters ${a}_{1}$, ${a}_{2}$,... Your aim is to find values for these parameters${a}_{i}$ such that $f(x)$ is infinitesimal to a required order, at the neighborhood of a given point ${x}_{0}$.

Except the trivial levels, one solves the problem by the Taylor expansion of $f(x)$. In the difficult cases, the resolution of a system of linear equations is also necessary.Choose the level of difficulty suitable for you: 1 . 2 . 3 . 4 . 5 . 6 . 7 . 8 .
