parabola|Conormal points

Point OF tangency , Properties OF normal, Conormal points,Chord OF contact , Illustration

If the tangent at the extrenities of a chord PQ of a parabola intersect at T, then the distances of the focus of the parabola from the points P.T. Q are in

If the sum of slopes of concurrent normals to the curve xy=4 is equal to the sum of ordinates of conormal points then locus of P is

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

Four standard parabolas || Position OF point with respect to parabola || Chord joining two point

Normal to Parabola and Co-Normal Points

The point of intersection of the tangents to the parabola at the points t_(1), and t_(2) is

If the normal to the parabola y^(2)=4ax at point t_(1) cuts the parabola again at point t_(2) .Then the minimum value of t_(2)^(2) is
