Le script contient deux fonctions concernant le calcul sur les vecteurs. La fonction coordinates(x_A,y_A,x_B,y_B) renvoie les coordonnées du vecteur AB avec A(x_A,y_A) et B(x_B,y_B). La fonction collinear(x_1,y_1,x_2,y_2) renvoie True si les vecteurs u(x_1,y_1) et v(x_2,y_2) sont colinéaires et False sinon.

from math import *
def coordinates(x_A,y_A,x_B,y_B):
  return x_B-x_A,y_B-y_A
def collinear(x_1,y_1,x_2,y_2):
  return x_1*y_2-x_2*y_1==0
