WebSimplifying gives us the formula for a parabola: x 2 = 4py. In more familiar form, with "y = " on the left, we can write this as: `y=x^2/(4p)` where p is the focal distance of the parabola. Now let's see what "the locus of points equidistant from a point to a line" means. Each of the colour-coded line segments is the same length in this spider ... WebThen you substitute the parabola's equation into the rotation equations: y = k* x^2 x' = x * cos (theta) - (kx^2) * sin (theta) y' = (kx^2) * cos (theta) + x * sin (theta) Theta is a known value, and everything else is given in terms of x, so you can use this information to …

WebNov 20, 2013 · This is the length of the focal chord (the "width" of a parabola at focal level). Let x 2 = 4 p y be a parabola. Then F ( 0, p) is the focus. Consider the line that passes through the focus and parallel to the directrix. Let A and A ′ be the intersections of the line and the parabola. Then A ( − 2 p, p), A ′ ( 2 p, p), and A A ′ = 4 p.
