"PQ focal chord of x^2 = 4ay, QT is the tangent at Q and TP is parallel to the axis of the parabola

T = (2ap, 2apq -aq^2)

i can do all the parts but cant do the last part of the question which states
(i) Show that the locus T = x^2 (y +2a) + 4a^3

Thankyou

Could you put the rest of the question up because it could be that you need one of the previous sections to answer the last question?

I think from the previous part of the question, he put up T = (2ap, 2apq - aq^2).
Except, there is nothing to substitute into 'q' to get rid of it, only 'p'... mmm
Post the whole question up Kutay?
