A parabola of latusrectum 4a slips between the coordinate axes.Find the locus of the focus and vertex
Hi,
and the equation of its directrix should be
and the perpendicular distance from direcrtrix to tangent at vertex is equal to a.
locus of focus is

Let (h,k) be the focus of the parabola, since it touches the axis tangent at the vertex should be
and the equation of its directrix should be
and the perpendicular distance from direcrtrix to tangent at vertex is equal to a.
locus of focus is
