Key Calculus Terms and definitions covered in this textbook
• Arrow

The notation PQ denoting the directed line segment with initial point P and terminal point Q.

• Binomial probability

In an experiment with two possible outcomes, the probability of one outcome occurring k times in n independent trials is P1E2 = n!k!1n - k2!pk11 - p) n-k where p is the probability of the outcome occurring once

• Boundary

The set of points on the “edge” of a region

• Bounded above

A function is bounded above if there is a number B such that ƒ(x) ? B for all x in the domain of ƒ.

• Central angle

An angle whose vertex is the center of a circle

• Equal matrices

Matrices that have the same order and equal corresponding elements.

• Geometric series

A series whose terms form a geometric sequence.

• Inequality

A statement that compares two quantities using an inequality symbol

• Limaçon

A graph of a polar equation r = a b sin u or r = a b cos u with a > 0 b > 0

• Logarithm

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

• Lower bound for real zeros

A number c is a lower bound for the set of real zeros of ƒ if ƒ(x) Z 0 whenever x < c

• Parametrization

A set of parametric equations for a curve.

• Polar coordinate system

A coordinate system whose ordered pair is based on the directed distance from a central point (the pole) and the angle measured from a ray from the pole (the polar axis)

• Positive linear correlation

See Linear correlation.

• Present value of an annuity T

he net amount of your money put into an annuity.

• Time plot

A line graph in which time is measured on the horizontal axis.

• Trigonometric form of a complex number

r(cos ? + i sin ?)

• Vertical asymptote

The line x = a is a vertical asymptote of the graph of the function ƒ if limx:a+ ƒ1x2 = q or lim x:a- ƒ1x2 = q.

• Vertical translation

A shift of a graph up or down.

• Weighted mean

A mean calculated in such a way that some elements of the data set have higher weights (that is, are counted more strongly in determining the mean) than others.
