Angular speed
Speed of rotation, typically measured in radians or revolutions per unit time

Arctangent function
See Inverse tangent function.

Composition of functions
(f ? g) (x) = f (g(x))

Continuous at x = a
lim x:a x a ƒ(x) = ƒ(a)

Convenience sample
A sample that sacrifices randomness for convenience

Equal matrices
Matrices that have the same order and equal corresponding elements.

Factor
In algebra, a quantity being multiplied in a product. In statistics, a potential explanatory variable under study in an experiment, .

Implicitly defined function
A function that is a subset of a relation defined by an equation in x and y.

Inductive step
See Mathematical induction.

Nautical mile
Length of 1 minute of arc along the Earth’s equator.

Negative linear correlation
