Key Calculus Terms and definitions covered in this textbook
• Augmented matrix

A matrix that represents a system of equations.

• 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 = sin-1 x

• Inverse variation

See Power function.

See Polynomial function in x.

• Linear programming problem

A method of solving certain problems involving maximizing or minimizing a function of two variables (called an objective function) subject to restrictions (called constraints)

• Logarithm

An expression of the form logb x (see Logarithmic function)

• Measure of center

A measure of the typical, middle, or average value for a data set

• Partial fractions

The process of expanding a fraction into a sum of fractions. The sum is called the partial fraction decomposition of the original fraction.

• Rational expression
