Key Words / FlashCards
| Key Words | Definitions (pref. in our own words) |
|---|---|
| Conic Sections | The curves obtained as intersections of a plane with a double napped right circular cone. |
| Right Circular Cone | Cone of whose axis passes through the center of the base. |
Learning aids / Gadgets
