Length of tangent from a Point to a Circle.

The length of tangent between the point of contact and the point where it meets the directrix subtends right angle at corresponding focus.

The length of tangent from the point (2,-3) to the circle 2x^(2)+2y^(2)=1 is

If length of tangent at any point on th curve y=f(x) intercepted between the point and the x -axis is of length 1. Find the equation of the curve.

If length of tangent at any point on the curve y=f(x) intercepted between the point and the x -axis is of length l. Find the equation of the curve.

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 sub-tangent at the point is
