WebAny conic may be determined by three characteristics: a single focus, a fixed line called the directrix, and the ratio of the distances of each to a point on the graph. Consider the parabola x = 2 + y2 shown in Figure 2. Figure 2 In The Parabola, we learned how a parabola is defined by the focus (a fixed point) and the directrix (a fixed line).

WebThe linear eccentricity (focal distance) is c = \sqrt {a^ {2} + b^ {2}} = 3 \sqrt {5} c = a2 + b2 = 3 5. The eccentricity is e = \frac {c} {a} = \frac {\sqrt {5}} {2} e = ac = 25. The first focus is \left (h - c, k\right) = \left (- 3 \sqrt {5}, 0\right) (h − c,k) = (−3 5,0). WebConic Sections Foldables Cheat Sheet HW and Graph Paper.

WebThis value is constant for any conic section, and can define the conic section as well: If e = 1, e = 1, the conic is a parabola. If e < 1, e < 1, it is an ellipse. If e > 1, e > 1, it is a hyperbola. The eccentricity of a circle is zero. The directrix of a conic section is the line that, together with the point known as the focus, serves to ...
