Pj and P2 of the segment Q1Q2 2. Find the point on the axis of x which, with the point(—1, 0), divides harmonically the segment of the axis joiningthe points (- 8, 0), (3, 0). 3. Exercise 1, for the four points Pi, P2, Qi, Q2 with therespective coordinates (2, 3), (—1, 9), (1, 5), (5, —3). .4. Find… … Fig. 20 and the point Pi: (xi, y^) are given. A line L is drawn through Pi meeting the ellipse in Q^ and Q2, and on L the point P: (X, Y) is marked which, with Pi, divides Q1Q2 harmonically. What is the locus of P, as L revolves about Pi ? Since Pi, P divide Q1Q2 harmonically, Q^, Q2 divide…
