Tip 73. Arguments of a plot – a vector

Fig. 73. Arguments of a plot – a vector

In the tip 29 two methods of construction of the X-Y Plot graph in Mathcad were described – three-cycle and two-cycle processes. But in a number of cases it is possible to construct a graph for one step.

In the fig. 73 the X-Y Plot is constructed where not functions and arguments (variables) but the vectors are written near the axes x and y. Every vector has four real arguments. In the fig. 73 the problem about a win of an “old woman” on roulette from “Gambler” of F.M. Dostoevsky is solved graphically (see the sketch “Mathcad and some secrets of literature” – http://twt.mpei.ac.ru/ochkov/Gerasim/Gerasim.htm).
