WebParabola. A parabola is defined as a collection of points such that the distance to a fixed point (the focus) and a fixed straight line (the directrix) are equal. But it's probably easier to remember it as the U-shaped … Webon the directrix is the difference of the y -values: d = y + p. The distance from the focus (0, p) to the point (x, y) is also equal to d and can be expressed using the distance formula. d = √(x − 0)2 + (y − p)2 = √x2 + (y − p)2. Set the two expressions for d equal to each other and solve for y to derive the equation of the parabola.
