Key Calculus Terms and definitions covered in this textbook
• Algebraic model

An equation that relates variable quantities associated with phenomena being studied

• Combination

An arrangement of elements of a set, in which order is not important

• Equivalent arrows

Arrows that have the same magnitude and direction.

• Event

A subset of a sample space.

• Focal length of a parabola

The directed distance from the vertex to the focus.

• Hyperboloid of revolution

A surface generated by rotating a hyperbola about its transverse axis, p. 607.

• Identity matrix

A square matrix with 1’s in the main diagonal and 0’s elsewhere, p. 534.

• Index

• Median (of a data set)

The middle number (or the mean of the two middle numbers) if the data are listed in order.

• Opens upward or downward

A parabola y = ax 2 + bx + c opens upward if a > 0 and opens downward if a < 0.

• Polar equation

An equation in r and ?.

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

• Randomization

The principle of experimental design that makes it possible to use the laws of probability when making inferences.

• Reference triangle

For an angle ? in standard position, a reference triangle is a triangle formed by the terminal side of angle ?, the x-axis, and a perpendicular dropped from a point on the terminal side to the x-axis. The angle in a reference triangle at the origin is the reference angle

• Removable discontinuity at x = a

lim x:a- ƒ(x) = limx:a+ ƒ(x) but either the common limit is not equal ƒ(a) to ƒ(a) or is not defined

• Slope

Ratio change in y/change in x

• Standard form of a complex number

a + bi, where a and b are real numbers

• Stem

The initial digit or digits of a number in a stemplot.

• Sum of an infinite geometric series

Sn = a 1 - r , |r| 6 1

• Zero factorial

See n factorial.
