The point (1,2) is one extremity of focal chord of parabola `y^(2)=4x` .The length of this focal chord is

If the point (at^(2),2at) be the extremity of a focal chord of parabola y^(2)=4ax then show that the length of the focal chord is a(t+(1)/(t))^(2)

If the point ( at^2,2at ) be the extremity of a focal chord of parabola y^2=4ax then show that the length of the focal chord is a(t+t/1)^2 .

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

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:

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) .

Number of focal chords of the parabola y^(2)=9x whose length is less than 9 is

(1/2,2) is one extremity of a focal of chord of the parabola y^(2)=8x The coordinate of the other extremity is

If " ((1)/(2),2) " is one extremity of a focal chord of parabola " y^(2)=8x " then other extremity is

If (-1,-2sqrt2) is one of exteremity of a focal chord of the parabola y^(2)=-8x, then the other extremity is
