How to solve for latus rectum
WebLatus rectum LL' passes through the focus (a, 0). Hence the point L is (a, y 1). There fore, y 1 2 = 4a(a) y 1 2 = 4a 2. Take square root on both sides. y 1 = ± √(4a 2) y 1 = ±2 a. y 1 = 2 a or -2a. The end points of latus rectum are … 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.
