Here you can get some pice of information about the function:
The intervall is displayed as well as the first and second
differentiation. Also the points where the function is zero, has a
min or max or a turning point.
For some functions, the differentiation is not correct for all
values. Table
shows the differentiations
that are used.
During a discussion, you can stop it with a mouse–click. You are asked
whether to continue or stop. You can do this for every one of the three
parts of a discussion.
