Angle of elevation
The acute angle formed by the line of sight (upward) and the horizontal

Bias
A flaw in the design of a sampling process that systematically causes the sample to differ from the population with respect to the statistic being measured. Undercoverage bias results when the sample systematically excludes one or more segments of the population. Voluntary response bias results when a sample consists only of those who volunteer their responses. Response bias results when the sampling design intentionally or unintentionally influences the responses

Compound interest
Interest that becomes part of the investment

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

Correlation coefficient
A measure of the strength of the linear relationship between two variables, pp. 146, 162.

Double inequality
A statement that describes a bounded interval, such as 3 ? x < 5

Expanded form of a series
A series written explicitly as a sum of terms (not in summation notation).

Frequency distribution
See Frequency table.

Index of summation

Main diagonal
The diagonal from the top left to the bottom right of a square matrix

Major axis
The line segment through the foci of an ellipse with endpoints on the ellipse

Onetoone rule of logarithms
x = y if and only if logb x = logb y.

Origin
The number zero on a number line, or the point where the x and yaxes cross in the Cartesian coordinate system, or the point where the x, y, and zaxes cross in Cartesian threedimensional space

Polar coordinates
The numbers (r, ?) that determine a point’s location in a polar coordinate system. The number r is the directed distance and ? is the directed angle
