Anyone good at parabolas? If so, Help please :)
(a) Write down the equation of the chord of contact of the parabola x^2 = 4ay from the point P(x0, y0 ), then write it in gradientâ€“intercept form y = mx + b.
(b) Let this chord meet the axis of the parabola at T, and let the line through P parallel to the axis meet the parabola at N. Use part (a) to show that:
(i) the points P and T are equidistant from the tangent at the origin,
(ii) the chord is parallel to the tangent to the parabola at N.
