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` .

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)

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

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

The Harmonic mean of the segments of a focal chord of the parabola y^(22)=4ax is
