The ordinate of a point on the parabola `y^2 =18x` is one third of its length of the latus-rectum. Then the equation of tangent at that point is

The ordinate of a point on the parabola y^2 =18x is one third of its length of the Latusrectum. Then the length of subtangent at the point is

" The ordinate of a point on the parabola " y^(2)=18x " is one third of its length of the latus rectum. Then the length of subtangent at the point is "

The point of intersection of the normals to the parabola y^(2)=4x at the ends of its latus rectum is

Let p be a point on the parabola y^(2)=4ax then the abscissa of p ,the ordinates of p and the latus rectum are in

The point (2a, a) lies inside the region bounded by the parabola x^(2) = 4y and its latus rectum. Then,

Let A be the vertex and L the length of the latus rectum of the parabola,y^(2)-2y-4x-7=0 The equation of the parabola with A as vertex 2L the length of the latus rectum and the axis at right angles to that of the given curve is:
