CALCUL VECTORIEL: DEMONTRER QUE DES DROITES SONT CONCOURANTES EN UTILISANT LE BARYCENTRE

In this video, we will see how to use the barycenter to prove that lines are concurrent. We will use the definition and properties of the barycenter. We will see how to use the partial barycenter theorem. We will determine the set of barycenters of two weighted points. We will see how to use the barycenter to prove the collinearity of three points. We will use the barycenter to prove that lines are concurrent. We will see how to plot points defined by vector equalities in the vector plane.
