  1. Identifying Conics

  2. General Form • + Cx + Dy + E = 0 • This can be used to identify certain characteristics about each type of conic

  3. + Cx + Dy + E = 0 This term complicates things… we’ll leave it for Precal. All conic sections can be written in the general form Ax2 + Bxy + Cy2 + Dx + Ey+ F = 0. All conic sections can be written in the general form Ax2 + Bxy + Cy2 + Dx + Ey+ F = 0. How many squared terms? Are and both present? Do they have the same sign? Do they havethe samecoefficients? two yes yes Circle one no Parabola no Hyperbola Ellipse

  4. ellipse • Identify each of the given conics ellipse hyperbola parabola parabola circle hyperbola ellipse parabola
