Exercise 5 Consider the following triangle. V- proju(v) 1. Prove that the area of this triangle is |u|||v| sin(0) 2. Compute the area of the triangle with the given vertices : A=(1,-1), B=(2,2) and C=(4,0). Indication for question 1: Find the base and the altitude, then use the fact that |v – proju(v)|| = ||sin(0).
