[" If one end of a focal chord of the parabola,"y^(2)=16x" is at "(1,4)" ,then the length of "],[" this focal chord is "]

If t is the parameter of one end of a focal chord of the parabola y^(2) = 4ax , show that the length of this focal chord is (t + (1)/(t))^(2) .

If (t^(2),2t) is one end ofa focal chord of the parabola,y^(2)=4x then the length of the focal chord will be:

PSQ is a focal chord of the parabola y^(2)=16x . If P=(1,4) then (SP)/(SQ)=

If one end of a focal chord of the parabola y^(2)=4ax be (at^(2),2at) , then the coordinates of its other end is

If (at^(2) , 2at) be the coordinate of an extremity of a focal chord of the parabola y^(2) =4ax, then the length of the chord is-

If t is a parameter of one end of a focal chord of the parabola y^(2) =4ax then its length is

One extremity of a focal chord of y^(2)=16x is A(1,4). Then the length of the focal chord at A is

the distance of a focal chord of the parabola y^(2)=16x from its vertex is 4 and the length of focal chord is k ,then the value of 4/k is

One end point of a focal chrod of a parabola y^(2)=16x is (1,4) . The length of focal chord is : (A)24 (B)25 (C)20 (D)=22

Let one end of focal chord of parabola y^2 = 8x is (1/2, -2) , then equation of tangent at other end of this focal chord is
