Key Calculus Terms and definitions covered in this textbook
• Acute angle

An angle whose measure is between 0° and 90°

• Angle

Union of two rays with a common endpoint (the vertex). The beginning ray (the initial side) can be rotated about its endpoint to obtain the final position (the terminal side)

• Causation

A relationship between two variables in which the values of the response variable are directly affected by the values of the explanatory variable

• Composition of functions

(f ? g) (x) = f (g(x))

• Descriptive statistics

The gathering and processing of numerical information

• Histogram

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

See Polynomial function in x.

• Line of symmetry

A line over which a graph is the mirror image of itself

• Logarithmic regression

See Natural logarithmic regression

• nth root of a complex number z

A complex number v such that vn = z

• Principal nth root

If bn = a, then b is an nth root of a. If bn = a and a and b have the same sign, b is the principal nth root of a (see Radical), p. 508.

The graph in three dimensions of a seconddegree equation in three variables.

• Range screen

See Viewing window.

• Reflection through the origin

x, y and (-x,-y) are reflections of each other through the origin.

• Statistic

A number that measures a quantitative variable for a sample from a population.

• Symmetric matrix

A matrix A = [aij] with the property aij = aji for all i and j

• Upper bound for real zeros

A number d is an upper bound for the set of real zeros of ƒ if ƒ(x) ? 0 whenever x > d.

• Venn diagram

A visualization of the relationships among events within a sample space.

• x-coordinate

The directed distance from the y-axis yz-plane to a point in a plane (space), or the first number in an ordered pair (triple), pp. 12, 629.

• Zero factorial

See n factorial.
