Proving Collinearity of Points Using Vector Methods

The video tutorial explains a vector problem involving a triangle OAB, where C is the midpoint of OA, D is on AB with a ratio of 3:1, and E is such that OB equals twice BE. The task is to prove that points C, D, and E are collinear using vector methods. The tutorial guides through diagram creation, vector calculations, and proof of collinearity, emphasizing careful processing of information and correct representation in diagrams.
