The coordinates of one end of a focal ch...

The coordinates of one end of a focal chord of the parabola `y^(2) = 4 ax ` are `(at^(2) , 2 at )` .prove that the coordinates of the other end must be `((a)/(t^(2)),-(2a)/(t))`.

Text Solution

Verified by Experts

The correct Answer is:
`(at_(1)^(2),2at_(1))=((a)/(t^(2)),-(2a)/(t)) [becauset^(1)=-(1)/(t)]`
