WebDefinition of a Parabola "A locus is a curve or other figure formed by all the points satisfying a particular equation.". One way we can define a parabola is that it is the locus of points that are equidistant from both a line called the directrix and a point called the focus.So each point P on the parabola is the same distance from the focus as it is from the directrix, as … WebThe simplest equation for a parabola is y = x2 Turned on its side it becomes y2 = x (or y = √x for just the top half) A little more generally: y 2 = 4ax where a is the distance from the …
WebOct 6, 2024 · To find the distance between the point (x, y) and the focus (h, k + p) we need to use the distance formula: d = √(x − h)2 + (y − (k + p))2 Then we set the two distances equal to each other: √(x − h)2 + (y − (k + p))2 = y − (k − p) Square both sides: (x − h)2 + (y − (k + p))2 = (y − (k − p))2 WebFinding the Focus and Directrix of a Parabola in Vertex Form Step 1: Identify h,k, h, k, and a a for the parabola in vertex form y =a(x−h)2+k y = a ( x − h) 2 + k through comparison of the...
