Focus (geometry) - Wikipedia

WebUnder the polar definition of conics, e is the constant ratio of the distance from a point to the focus and the distance from that point to the directrix. Ellipse The set of all points such that the sum of the distances from the point to each of two fixed points is constant. Focus WebIt turns out that all conic sections (circles, ellipses, hyperbolas, and parabolas) can be defined using a single relationship. Conic Sections General Definition A conic section can be defined by placing a fixed point at the origin, F( )0,0 , called the focus, and drawing a line L called the directrix at x = ± p or y = ± p.

WebA conic section is the intersection of a plane and a double right circular cone . By changing the angle and location of the intersection, we can produce different types of conics. There are four basic types: circles , … WebThe focus is a point on a graph and the directrix is a line. Every point on that line is as close to the focus as it is to the directrix, or as Sal says, "equidistant". If you are doing precalculus, you probably know the pythagorean theorem. a^2 + b^2 = c^2.
