Coïncidence-EquaDiff is a graphical mathematical exercise-game
designed to teach you the relation between linear
differential equations
and the curves of their solutions.

**Principle** :

You will see two curves of different colors on the screen representing
two solutions of differential equations: one is given by the server,
the other constructed by you.

Your goal is to modify the coefficients of your equation, to make
the curve coincide with that of the computer.

You have the right to several tries.The most important is to find the good solution at the end.
