WebMar 21, 2024 · Equation of Latus Rectum of a Parabola. Suppose there is a parabola with the standard equation of parabola: y 2 = 4 a x. For this, the focus of the parabola is located at the position (a,0) and the directrix intersects the axis of the parabola at (-a,0). Thus, for this parabola, the equation of the latus rectum is: y = x − a.

WebTo work with parabolas in the coordinate plane, we consider two cases: those with a vertex at the origin and those with a vertex at a point other than the origin. We begin with the former. Let (x,y) ( x, y) be a point on the parabola with vertex (0,0) ( 0, 0), focus (0,p) ( 0, p), and directrix y =−p y = − p as shown in Figure 4.
