So, okay I don't even know what the question means. I'm so confused now..

Consider the parabola , where and suppose the tangents at and intersect at point T.

Let be the focus of the parabola.

1) Find the coordinates of T. (assume that the tangents at P is ).

2) Show that . Suppose P and Q move on the parabola in such a way that

3) Show that T is constrained to move on a parabola
