Station 1: Write the equation for a circle with a diameter that has endpoints of (1, 5) and (12, -2). Station 2: Find an equation for the hyperbola with center at (1, -2) and vertices at (4, -2) and (-2, -2), with a conjugate axis of length 10. Station 3: Determine an equation for the parabola with focus (3, 6) and directrix y = -2. Station 4: Find the vertex, focus, directrix and focal width of the parabola with equation , then graph it. Station 5: Determine an equation for the parabola with vertex (2, 4) and focus (0, 4). Station 6: Determine the major and minor vertices, center, and foci of the ellipse , then graph it. Station 7: Determine what type of conic is, then identify all key information and graph it. Station 8:

An ellipse is the set of points such that the sum of the distances from any point on the ellipse to two other fixed points is constant. The two fixed points are called the foci (plural of focus) of the ellipse. Figure %: The sum of the distances d1 + d2 is the same for any point on the ellipse. The line segment containing the foci of an ellipse with both endpoints on the ellipse is called the major axis. The endpoints of the major axis are called the vertices. The point halfway between the foci is the center of the ellipse. The line segment perpendicular to the major axis and passing through the center, with both endpoints on the ellipse, is the minor axis.

Analytic geometry is roughly the same as plane geometry except that in analytic geometry, figures are studied in the context of the coordinate plane. Instead of focusing on the congruence of shapes like plane geometry, analytic geometry deals with the coordinates of shapes and formulas for their graphs in the coordinate plane. Much of analytic geometry focuses on the conics. A conic is a two-dimensional figure created by the intersection of a plane and a right circular cone. All conics can be written in terms of the following equation: Ax2 + Bxy + Cy2 + Dx + Ey + F = 0 . The four conics we'll explore in this text are parabolas, ellipses, circles, and hyperbolas.

Hyperbolas don't come up much ? at least not that I've noticed ? in other math classes, but if you're covering conics, you'll need to know their basics. An hyperbola looks sort of like two mirrored parabolas, with the two "halves" being called "branches". Like an ellipse, an hyperbola has two foci and two vertices; unlike an ellipse, the foci in an hyperbola are further from the hyperbola's center than are its vertices:
