Focus conic sections
WebThe focus is at (h, k + p). The directrix is the line y = k - p. The axis is the line x = h. If p > 0, the parabola opens upward, and if p < 0, the parabola opens downward. If a parabola has a horizontal axis, the standard form … WebWe need those for the following: Proposition 1: Let F = (xF: yF: 1) be a real finite focus of a non-degenerate conic section with real coefficients. Let zF = xF + iyF where i is the …

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 ...
