written algorithm is that in a program, names will be given to the expressions which appear several times, to avoid to compute them several times. For better readability, names have been given only to the quantities whose sign or equality to 0 have to be tested. I do not see any way to improve the algorithmic aspect of this page, while keeping a good readability, especially for beginners. Note that the first general formula is not useful from a logical point of view, and could thus be suppressed. But it has to appear, as it is the formula which is the most popular.
2092:: The geometric interpretation given in the caption of the figure at the top of the article should be recalled here. As given here, the geometric interpretation of Vieta's trigonometric formula appears to be simply an explanation of what a cosine and an arccosine are. Thus a figure is needed on which an equilateral triangle inscribed in a circle appears, whose edges project on the roots. A further explanation is needed, showing how the circle and the angle which has to be trisected may be graphically constructed.
2106:: As written, the object of this section is not clear, as it consider the roots as given. Thus I would have began it as: "With one real and two complex roots, the three roots can be represented as points in the complex plane, as well as the two roots of the derivative. There is an interesting relationship between all these roots ... " One may add somewhere the fact that the roots of the derivative are real or complex depending if the summit angle of the triangle is smaller or larger than

6429:: The remark of the IP user is worthwhile, even if it is not well expressed: All the displayed cubics have the same shape: two real roots for the derivative and a positive third derivative (leading coefficient). It would be useful to display all the four different possible shapes (in fact 6 if one counts the cases of a double root of the derivative).
