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

If one end of a focal chord "AB" of the parabola y^(2)=8x is at "A((1)/(2),-2) " then the equation of the tangent to it at "B" is ax+by+8=0" .Find a+b

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 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 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)

If (2,-8) is at an end of a focal chord of the parabola y^(2)=32x, then find the other end of the chord.
