Thanks for the help. Appreciate it :D

Sorry :( I have one last question: If the chord of contact of the tangents to the parabola x^2=4ay from an external point T(x1,y1) meets the directrix at R, prove that RT subtends a right angle at the focus.

Thanks a lot! You saved me :D

Hi, I was wondering if anyone could help me with these questions... i'd really appreciate any help asap :) thanx The line L passes through the focus of x^2=4ay and makes an angle of 45 with the x axis. (a) Find the equation of L. (b) If P is the point (2ap, ap^2) on the parabola and Q is a...
