Conic section (or conic)
A curve obtained by intersecting a doublenapped right circular cone with a plane

Equivalent equations (inequalities)
Equations (inequalities) that have the same solutions.

Expanded form
The right side of u(v + w) = uv + uw.

Halflife
The amount of time required for half of a radioactive substance to decay.
