Well the only relation I got was p-q=1 +pq But I still don't know know what to do with it...

Ok I'm stuck again... I'm terrible at this =.= It's the next part of that question. It says: By evaluating the espression x^2 = 4ay at T (which is pt of intersection I found is (a(p+q),apq)), or otherwise, find the locus of T when the tangents at P and Q intersect. I tried using x=a(p+q)...

Thank you very much, I understand it now :)

Omg I forgot all about that formula. Thank you very much.

I need help with this question. I don't know what to do with the angle?? You are given the tangents at P and Q (which I found was y=px - ap^2 & y=qx -aq^2) intersect at an angle of 45. Show that p-q= 1 + pq. Thanks in advance.

Please help me with these questions. I don't know how to do it =.= 1. Prove that the tangents at the end of a focal chord are perpendicular. 2. Show that the tangents at the ends of a focal chord interesct on the directrix. Thanks in advance!

Thank you very much! :) I get it now

I really need help answering these questions... I don't really know what to do first =.= Can someone please talk me through the steps I should take to do these questions?? Thank you in advance 1. When 50ml of 1.0mol/L potassium hydroxide solution is added to 50ml of 1.0mol/L hydrochloric...
