Key Calculus Terms and definitions covered in this textbook
• Control

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

• Divisor of a polynomial

See Division algorithm for polynomials.

• Fitting a line or curve to data

Finding a line or curve that comes close to passing through all the points in a scatter plot.

• Geometric sequence

A sequence {an}in which an = an-1.r for every positive integer n ? 2. The nonzero number r is called the common ratio.

• Integers

The numbers . . ., -3, -2, -1, 0,1,2,...2

• Linear system

A system of linear equations

• Negative association

A relationship between two variables in which higher values of one variable are generally associated with lower values of the other variable.

• Partial fractions

The process of expanding a fraction into a sum of fractions. The sum is called the partial fraction decomposition of the original fraction.

• Pie chart

See Circle graph.

• 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)

• Power-reducing identity

A trigonometric identity that reduces the power to which the trigonometric functions are raised.

• Range of a function

The set of all output values corresponding to elements in the domain.

• Range screen

See Viewing window.

• Sample space

Set of all possible outcomes of an experiment.

• Sample survey

A process for gathering data from a subset of a population, usually through direct questioning.

• Solve algebraically

Use an algebraic method, including paper and pencil manipulation and obvious mental work, with no calculator or grapher use. When appropriate, the final exact solution may be approximated by a calculator

• Solve by substitution

Method for solving systems of linear equations.

• Sum of a finite arithmetic series

Sn = na a1 + a2 2 b = n 2 32a1 + 1n - 12d4,

A graph in which (x, -y) is on the graph whenever (x, y) is; or a graph in which (r, -?) or (-r, ?, -?) is on the graph whenever (r, ?) is

• 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.
