Across
- 4. This number can be attached to any conic section, and gives a sort of indication of how much a conic section varies from being circular. As this increases, the conic section becomes more “un-circular”.
- 10. Another way aside from addition, subtraction, multiplication, and division, to put two or more functions together to form another function.
- 12. These are the endpoints of the major axis of the ellipse.
- 13. The fixed point mentioned in the definition of a parabola.
- 16. Name of the student
- 20. A line segment perpendicular to the transverse axis through the center of the hyperbola. The length of this other line segment that is associated with hyperbolas is 2b.
- 22. The branches of these lines appear to approach two intersecting lines as the values of x and y increase pass through the corners of a 2a by 2b rectangle.
- 23. Functions that are represented by a combination of equations, each corresponding to a part of the domain. In these functions, each piece of equation behaves differently based on the domain set or assigned to each piece.
- 24. These are what the resulting cross-sections are called if a plane cuts a cone.
- 25. This is what one half of a double cone is called.
- 26. A point on the parabola that is the midway of the focus and the directrix.
Down
- 1. These three cases of conics include a point, a line, and two intersecting lines.
- 2. The resulting conic section when the intersecting plane intersects both nappes of a cone and is parallel to two generators.
- 3. This passes through the center of the ellipse and is perpendicular to the major axis. It is also the shorter of the two line segments.
- 5. The resulting function when composition is applied.
- 6. Name of the teacher
- 7. The line segment joining the two vertices of a hyperbola. Its midpoint is called the center of the hyperbola.
- 8. A rule that assigns to each element x in a set C exactly one element y, usually denoted by f(x), in a set D. This is also usually defined as the sums, differences, products, and quotients of various expressions.
- 9. The line that passes through the focus and the vertex of a parabola.
- 11. The fixed line mentioned in the definition of a parabola.
- 14. The fixed distance between the center of a circle and its circumference.
- 15. The set of points in a plane that is equidistant from a fixed point and a fixed line.
- 17. This is the line segment that connects the two vertices of an ellipse.
- 18. A set of points on a plane whose sum of distances from two fixed points is a constant. These can also be found in nature, like in the orbits of planets.
- 19. Any line that lies on the cone.
- 21. A set of points equidistant from a fixed point.
- 24. The midpoint of the foci in an ellipse.
