This module is an exercise on the graphical recognition of the derivative of a function.
The server will give you the curve of a continuous and differentiable function on the interval [-2,2]. This function is randomly generated by the server, and its expression is hidden from you. You will then be presented with a certain number of other curves, and have to recognize among them that of the derivative function (or one of , ou , according to the configuration of the exercise). To send the reply, you can simply click on the curve which you think is the good one.
