Algebraic model
An equation that relates variable quantities associated with phenomena being studied

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

Circular functions
Trigonometric functions when applied to real numbers are circular functions

Convergence of a series
A series aqk=1 ak converges to a sum S if imn: q ank=1ak = S

Data
Facts collected for statistical purposes (singular form is datum)

Frequency
Reciprocal of the period of a sinusoid.

Imaginary axis
See Complex plane.

Inequality symbol or
<,>,<,>.

Initial point
See Arrow.

Linear inequality in x
An inequality that can be written in the form ax + b < 0 ,ax + b … 0 , ax + b > 0, or ax + b Ú 0, where a and b are real numbers and a Z 0

Natural logarithm
A logarithm with base e.

Polynomial function
A function in which ƒ(x)is a polynomial in x, p. 158.

Radian
The measure of a central angle whose intercepted arc has a length equal to the circle’s radius.
