Give an example of a function with one critical point which is also an inflection point. You must provide the equation of your function. Give an example of a function that satisfies \(f(-1)=f(1)=0\) ...

Plotting a graph takes time. Often mathematicians just want to know the key features. These are: shape, location and some key points (such as where the graph crosses the axes or turning points).

While I was checking out News YCombinator website (a good source of fresh news, by the way), I came across a rather plain page (full specifications as PDF file) When I was a kid I liked to draw ...
