The formula to find the length of latus rectum is 4a. The same goes for all of the other distances from a point on the parabola to the focus and directrix l_2 l_3 text etc. The quadratic equation is sometimes also known as the standard form formula of a parabola.
So the arc length of the parabola over the interval 0 x a is.
The ends of the latus rectum of a hyperbola are ae b 2 a 2 and the length of the latus rectum is 2b2a. A is the length along the parabola axis. The ends of the latus rectum of a hyperbola are ae b 2 a 2 and the length of the latus rectum is 2b2a. 0 This is the answer to the question but it would be more useful to us if we.
