What is Latus Rectum?
In geometry, the latus rectum of a parabola is the chord passing through the focus and perpendicular to the axis of symmetry. For a parabola defined by the equation $$y^2 = 4px$$, where p is the distance from the vertex to the focus, the length of the latus rectum is given by the formula: $$LR = 4|p|$$. It provides a measure of the "width" of the parabola at its focus. This calculator helps you find this length by simply providing the distance p.
