Na figura 15, apresenta-se uma atividade com uma animacao grafica que representa a translacao de uma circunferencia paralelamente ao eixo das abscissas, simulando uma bicicleta andando em um plano, desenvolvida com os softwares winplot e flash, para o nodo Conversao da Representacao Grafica para a Representacao Algebrica da Cincunferencia, na qual o aluno deveria escrever a equacao que representa a animacao grafica, de acordo com o exemplo em vermelho que utiliza o registro algebrico, enquanto sao escritas equates no software winplot.
Observe that a zooming operation means rescaling by the same amount abscissas and ordinates like seeing the intersection point as using magnifying glasses of increasing power.
The latter ones bear the following properties: such a hyperbola intersects with the respective straight hyperbola at the ordinate y = 0.5 and the abscissa equal to the double mass of the element; the line y = 0.5 is the axis of symmetry for the arcs; the real and tangential lines of such hyperbolas meet each other; the normal of such a hyperbola is the real axis and the tangential line of another hyperbola of this kind.

Let f be the abscissas of all points in a plane and g be the ordinates of these points, then h = f [disjunction] g is the set of coordinates of all points in the plane.
