Express the area of a triangle given by vertices, A(x_1,y_1), B(x_2,y_2), C(x_3,y_3). Show that it can be expressed as determinant of: det(Delta) = [(1, 1, 1 ),(x_1, x_2, x_3),(y_1, y_2, y_3) ].Calculate
If x_1, x_2, x_3 and y_1, y_2, y_3 are both in G.P. with the same common ratio then the points (x... - YouTube
