The sum of the slopes of the tangents to the parabola y2 = 8x drawn from the point (-2,3) is
The tangent to y2 = ax makes an angle 450 with x- axis. Then its point of contact is
Through the vertex O of the parabola y2 = 4ax a perpendicular is drawn to any tangent meeting it at P and the parabola at Q.Then OP.OQ =
The locus of the point of intersection of two tangents to the parabola y2 = 4ax which make complementary angles wit the axis of the parabola is
If the distance of two points P and Q on the parabola y2 = 4ax are 4 and 9 respectively,then 9 respectively,then the distance of the point of intersection of the tangents at P and Q fro the focus is
The line y = m(x + a)+a/m touch the parabola y2= 4a(x+ a) form
If the line x + y + 2 = 0 touches the parabola y2 = kx, then k =
The point of contact of 2x – y + 2 = 0 to the parabolay2 = 16x is
If the tangents and normals at the extremities of a focal chord of a parabola intersect at (x1,y1) and (x2,y2) respectively, then
the equation of the parabola whose vertex is at (0,0) and focus is the point of intersection of x+y =2, 2x –y = 4 is
