Curve Class
Detetesto as vitimas
Quando elas respeitam os seus carrascos.
Jean Paul Sartre

  • Circles:
    • Equation:
      [; (x-x_c)^2+(y-y_c)^2=r^2 ;]
    • Parametrization:
      [; \left( \begin{array}{c} x(t)\\y(t) \end{array}\right) = \left( \begin{array}{c} x_c+r \cos{t}\\y_c+r \sin{t} \end{array}\right) ;]
Python Listing: Circle.py. 
class Circle(Curve):

    self.C=Vector([1.0,1.0])
    self.r=2.0

    def Circle(t):
        return self.C+Vector([ cos(t),sin(t) ]*self.r
