The normal at the point `(b t_(1)^(2), 2b t_(1))` on a parabola meets the parabola again in the point `(b t_(2)^(2), 2b t_(2))` then

The normal at the point (bt_(1)^(2),2bt_(1)) on the parabola y^(2)=4bx meets the parabola again in the point (bt_(2)^(2),2bt_(2),) then

The normal drawn at a point (at_(1)^(2),-2at_(1)) of the parabola y^(2)=4ax meets it again in the point (at_(2)^(2),2at_(2)), then t_(2)=t_(1)+(2)/(t_(1))(b)t_(2)=t_(1)-(2)/(t_(1))t_(2)=-t_(1)+(2)/(t_(1))(d)t_(2)=-t_(1)-(2)/(t_(1))

" If the normal at the point " t_(1)(at_(1)^(2),2at_(1)) " on " y^(2)=4ax " meets the parabola again at the point " t_(2) " ,then " t_(1)t_(2) =

If the normals drawn at the points t_(1) and t_(2) on the parabola meet the parabola again at its point t_(3) , then t_(1)t_(2) equals.

Find the angle at which normal at point P(at^(2),2at) to the parabola meets the parabola again at point Q.

If the normal at(1, 2) on the parabola y^(2)=4x meets the parabola again at the point (t^(2), 2t) then the value of t, is

If the normals at P(t_(1))andQ(t_(2)) on the parabola meet on the same parabola, then
