Full solutions for Calculus | 9th Edition
Addition principle of probability.
P(A or B) = P(A) + P(B) - P(A and B). If A and B are mutually exclusive events, then P(A or B) = P(A) + P(B)
An arrangement of elements of a set, in which order is not important
Conic section (or conic)
A curve obtained by intersecting a double-napped right circular cone with a plane
Equivalent equations (inequalities)
Equations (inequalities) that have the same solutions.
The right side of u(v + w) = uv + uw.
The amount of time required for half of a radioactive substance to decay.
A shift of a graph to the left or right.
A set of points in a plane, the absolute value of the difference of whose distances from two fixed points (the foci) is a constant.
