Key Calculus Terms and definitions covered in this textbook

If u < v , then u + w < v + w

• Combinatorics

A branch of mathematics related to determining the number of elements of a set or the number of ways objects can be arranged or combined

• Compound fraction

A fractional expression in which the numerator or denominator may contain fractions

• Compounded continuously

Interest compounded using the formula A = Pert

• Correlation coefficient

A measure of the strength of the linear relationship between two variables, pp. 146, 162.

• Domain of validity of an identity

The set of values of the variable for which both sides of the identity are defined

• Equilibrium price

See Equilibrium point.

• Inverse secant function

The function y = sec-1 x

• Law of cosines

a2 = b2 + c2 - 2bc cos A, b2 = a2 + c2 - 2ac cos B, c2 = a2 + b2 - 2ab cos C

• Limit to growth

See Logistic growth function.

• Parabola

The graph of a quadratic function, or the set of points in a plane that are equidistant from a fixed point (the focus) and a fixed line (the directrix).

• Pseudo-random numbers

Computer-generated numbers that can be used to approximate true randomness in scientific studies. Since they depend on iterative computer algorithms, they are not truly random

• Quartic function

A degree 4 polynomial function.

• Reference angle

See Reference triangle

• Riemann sum

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

• Right circular cone

The surface created when a line is rotated about a second line that intersects but is not perpendicular to the first line.

• Row operations

See Elementary row operations.

• Solution of a system in two variables

An ordered pair of real numbers that satisfies all of the equations or inequalities in the system

• 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,
