Question: The points P ( a(p^2) | 2ap ) and Q ( a(q^2) | 2aq ) lie on the parabola with equation y^2 = 4ax. The

The points P ( a(p^2) | 2ap ) and Q ( a(q^2) | 2aq ) lie on the parabola with equation y^2 = 4ax.

The tangents to the parabola at P and Q meet at R [ apq | a(p+q) ].

Show that the area of triangle PQR is 1/2 * a^2 |p-q |^3 .

Please show every step and write the method usedplease.

Thank you.
