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.

• Ellipse

The set of all points in the plane such that the sum of the distances from a pair of fixed points (the foci) is a constant

• Empty set

A set with no elements

• Explicitly defined sequence

A sequence in which the kth term is given as a function of k.

• Factor

In algebra, a quantity being multiplied in a product. In statistics, a potential explanatory variable under study in an experiment, .

• Head minus tail (HMT) rule

An arrow with initial point (x1, y1 ) and terminal point (x2, y2) represents the vector <8x 2 - x 1, y2 - y19>

• Infinite sequence

A function whose domain is the set of all natural numbers.

• Interquartile range

The difference between the third quartile and the first quartile.

• Line of symmetry

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

• Linear inequality in two variables x and y

An inequality that can be written in one of the following forms: y 6 mx + b, y … mx + b, y 7 mx + b, or y Ú mx + b with m Z 0

• Multiplication principle of probability

If A and B are independent events, then P(A and B) = P(A) # P(B). If Adepends on B, then P(A and B) = P(A|B) # P(B)

• Power regression

A procedure for fitting a curve y = a . x b to a set of data.

An angle in standard position whose terminal side lies on an axis.

The measure of an angle in radians, or, for a central angle, the ratio of the length of the intercepted arc tothe radius of the circle.

• 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

• Riemann sum

A sum where the interval is divided into n subintervals of equal length and is in the ith subinterval.

• Symmetric property of equality

If a = b, then b = a

• Vertices of an ellipse

The points where the ellipse intersects its focal axis.

• Viewing window

The rectangular portion of the coordinate plane specified by the dimensions [Xmin, Xmax] by [Ymin, Ymax].

• Zero factorial

See n factorial.
