Question

how to.calculate end points of focal chord of a parabola​

Answer 1

Answer:

Step-by-step explanation:

The chord of the parabola which passes through the focus is called the focal chord. Any chord to y 2 = 4ax which passes through the focus is called a focal chord of the parabola y 2 = 4ax. Let y 2 = 4ax be the equation of a parabola and (at 2, 2at) a point P on it.

Answer 2

Answer:

In general, the endpoints of any focal chord of a parabola with vertex at V(h,k) V ( h , k ) that opens to the left/right are P(h+at2,k+2at) and Q(h+at2,k−2at) P ( h + a t 2 , k + 2 a t ) and Q ( h + a t 2 , k − 2 a t )
