Key Calculus Terms and definitions covered in this textbook
• Additive inverse of a real number

The opposite of b , or -b

• Axis of symmetry

See Line of symmetry.

• Complements or complementary angles

Two angles of positive measure whose sum is 90°

• Control

The principle of experimental design that makes it possible to rule out other factors when making inferences about a particular explanatory variable

• Derivative of ƒ

The function defined by ƒ'(x) = limh:0ƒ(x + h) - ƒ(x)h for all of x where the limit exists

• Finite sequence

A function whose domain is the first n positive integers for some fixed integer n.

• Five-number summary

The minimum, first quartile, median, third quartile, and maximum of a data set.

• Inequality

A statement that compares two quantities using an inequality symbol

• Initial point

See Arrow.

• Length of a vector

See Magnitude of a vector.

• Line graph

A graph of data in which consecutive data points are connected by line segments

• Local extremum

A local maximum or a local minimum

• Magnitude of an arrow

The magnitude of PQ is the distance between P and Q

• Mathematical induction

A process for proving that a statement is true for all natural numbers n by showing that it is true for n = 1 (the anchor) and that, if it is true for n = k, then it must be true for n = k + 1 (the inductive step)

• Median (of a data set)

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

• 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)

• Polynomial in x

An expression that can be written in the form an x n + an-1x n-1 + Á + a1x + a0, where n is a nonnegative integer, the coefficients are real numbers, and an ? 0. The degree of the polynomial is n, the leading coefficient is an, the leading term is anxn, and the constant term is a0. (The number 0 is the zero polynomial)

• Reflection through the origin

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

• Scientific notation

A positive number written as c x 10m, where 1 ? c < 10 and m is an integer.

• Upper bound for ƒ

Any number B for which ƒ(x) ? B for all x in the domain of ƒ.
