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

Bounded
A function is bounded if there are numbers b and B such that b ? ƒ(x) ? B for all x in the domain of f.

Center
The central point in a circle, ellipse, hyperbola, or sphere

Identity function
The function ƒ(x) = x.

Inverse secant function
The function y = sec1 x

Limit to growth
See Logistic growth function.

Linear correlation
A scatter plot with points clustered along a line. Correlation is positive if the slope is positive and negative if the slope is negative

Linear function
A function that can be written in the form ƒ(x) = mx + b, where and b are real numbers

Logarithm

Order of magnitude (of n)
log n.

Orthogonal vectors
Two vectors u and v with u x v = 0.

Perpendicular lines
Two lines that are at right angles to each other

Quotient rule of logarithms
logb a R S b = logb R  logb S, R > 0, S > 0

Reciprocal identity

Second
Angle measure equal to 1/60 of a minute.

Sequence
See Finite sequence, Infinite sequence.

Stemplot (or stemandleaf plot)
An arrangement of a numerical data set into a specific tabular format.

Upper bound for real zeros
A number d is an upper bound for the set of real zeros of ƒ if ƒ(x) ? 0 whenever x > d.

Upper bound test for real zeros
