Diameter of a parabola
WebThe general equation of a parabola is: y = a (x-h) 2 + k or x = a (y-k) 2 +h, where (h,k) denotes the vertex. The standard equation of a regular parabola is y 2 = 4ax. Some of the important terms below are helpful to understand the features and parts of a parabola. Focus: The point (a, 0) is the focus of the parabola. WebAn equation of a parabola is given. x^2 = 4y (a) Find the focus, directrix, and focal diameter of the parabola. focus (x, y) = (0,1) directrix y = -1 focal diameter (b) Sketch a graph of the parabola and its directrix.

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.
