Algebra II: Conic Sections - Chapter Summary and Learning Objectives

Put your graphing and algebraic problem-solving abilities to the test with this chapter on conic sections. Instructors show you how these skills, along with a working knowledge of vertices, foci and directrices, can be used to graph and write equations for conic sections. By the end of this chapter, you should be able to do the following:

  • Define ellipse, circle, hyperbola and parabola
  • Identify conic sections' foci and vertices
  • Graph conic sections centered at various points on the coordinate plane
  • Write the equation for a conic section in standard form
