CHECK THE SOLUTION.
→ (s), → (r), → (q), → (p)
Sol. 
Equation AB
y – 2at 1 = 
AB is a normal chord t 2 = – t 1 – 
AB is a focal chord t 1 t 2 = – 1
AB subtends 90º at the origin then = 
= – 1
= – 1
t 1 t 2 = – 4 ⇒ t 2 = 
AB is inclinded at 45° to the axis then slope 
= 1
t 1 + t 2 = 2
t 2 = – t 1 + 2
