Complex fraction
See Compound fraction.

Distance (in a coordinate plane)
The distance d(P, Q) between P(x, y) and Q(x, y) d(P, Q) = 2(x 1  x 2)2 + (y1  y2)2

DMS measure
The measure of an angle in degrees, minutes, and seconds

Equilibrium price
See Equilibrium point.

Explanatory variable
A variable that affects a response variable.

Histogram
A graph that visually represents the information in a frequency table using rectangular areas proportional to the frequencies.

Inequality
A statement that compares two quantities using an inequality symbol

Inferential statistics
Using the science of statistics to make inferences about the parameters in a population from a sample.

Instantaneous velocity
The instantaneous rate of change of a position function with respect to time, p. 737.

Inverse sine function
The function y = sin1 x

Inverse variation
See Power function.

Leading term
