Acute angle
An angle whose measure is between 0° and 90°

Arrow
The notation PQ denoting the directed line segment with initial point P and terminal point Q.

Boundary
The set of points on the “edge” of a region

Bounded below
A function is bounded below if there is a number b such that b ? ƒ(x) for all x in the domain of f.

Complex conjugates
Complex numbers a + bi and a  bi

Control
The principle of experimental design that makes it possible to rule out other factors when making inferences about a particular explanatory variable

Equation
A statement of equality between two expressions.

Exponent
See nth power of a.

Exponential form
An equation written with exponents instead of logarithms.

Limit to growth
See Logistic growth function.

Logarithmic form
An equation written with logarithms instead of exponents

Permutation
