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

See Inverse secant function.

p = g(x), where x represents demand and p represents price

The distance d(P, Q) between P(x, y) and Q(x, y) d(P, Q) = 2(x 1 - x 2)2 + (y1 - y2)2

a(b + c) = ab + ac and related properties

A method for solving equations in the form x 2 = k.

See Ellipse, Hyperbola, Parabola.

See Radical.

Using the science of statistics to make inferences about the parameters in a population from a sample.

The function y = sec-1 x

Equation of a linear regression line

See Natural logarithmic regression

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)

A measure of the typical, middle, or average value for a data set

Real numbers shown to the left of the origin on a number line.

A process for gathering data from a subset of a population through current or past observations. This differs from an experiment in that no treatment is imposed.

For a basic trigonometric function f, an identity relating f(x) to f(-x).

If bn = a, then b is an nth root of a. If bn = a and a and b have the same sign, b is the principal nth root of a (see Radical), p. 508.

A procedure used to divide a polynomial by a linear factor, x - a

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.
