WebApr 22, 2024 · For a parabola with $F(0,0)$ and directrix $y=-p$, first write a “distance equation” relating any point on the parabola, $P(x,y)$, to $F$ and to the directrix, $D$. WebMay 1, 2024 · Set the two expressions for d equal to each other and solve for y to derive the equation of the parabola. We do this because the distance from (x, y) to (0, p) equals the distance from (x, y) to (x, − p). √x2 + (y − p)2 = y + p We then square both sides of the equation, expand the squared terms, and simplify by combining like terms.
