Categorical variable
In statistics, a nonnumerical variable such as gender or hair color. Numerical variables like zip codes, in which the numbers have no quantitative significance, are also considered to be categorical.

Constant function (on an interval)
ƒ(x 1) = ƒ(x 2) x for any x1 and x2 (in the interval)

Cosecant
The function y = csc x

Derivative of ƒ
The function defined by ƒ'(x) = limh:0ƒ(x + h)  ƒ(x)h for all of x where the limit exists

General form (of a line)
Ax + By + C = 0, where A and B are not both zero.

Horizontal translation
A shift of a graph to the left or right.

Implied domain
The domain of a function’s algebraic expression.

Index of summation
See Summation notation.

Initial value of a function
ƒ 0.

Linear regression line
The line for which the sum of the squares of the residuals is the smallest possible

Natural logarithmic function
The inverse of the exponential function y = ex, denoted by y = ln x.

nth root of a complex number z
A complex number v such that vn = z

Objective function
See Linear programming problem.

Phase shift
See Sinusoid.

Polar equation
An equation in r and ?.

Polar form of a complex number
See Trigonometric form of a complex number.

Symmetric about the origin
A graph in which (x, y) is on the the graph whenever (x, y) is; or a graph in which (r, ?) or (r, ? + ?) is on the graph whenever (r, ?) is

Tangent
The function y = tan x

Translation
See Horizontal translation, Vertical translation.
