Key Calculus Terms and definitions covered in this textbook
• Bias

A flaw in the design of a sampling process that systematically causes the sample to differ from the population with respect to the statistic being measured. Undercoverage bias results when the sample systematically excludes one or more segments of the population. Voluntary response bias results when a sample consists only of those who volunteer their responses. Response bias results when the sampling design intentionally or unintentionally influences the responses

• Commutative properties

a + b = b + a ab = ba

• Coterminal angles

Two angles having the same initial side and the same terminal side

• Difference identity

An identity involving a trigonometric function of u - v

• Directrix of a parabola, ellipse, or hyperbola

A line used to determine the conic

• Frequency table (in statistics)

A table showing frequencies.

• Graph of an inequality in x and y

The set of all points in the coordinate plane corresponding to the solutions x, y of the inequality.

• Imaginary part of a complex number

See Complex number.

• Intermediate Value Theorem

If ƒ is a polynomial function and a < b , then ƒ assumes every value between ƒ(a) and ƒ(b).

• Nappe

See Right circular cone.

• NDER ƒ(a)

See Numerical derivative of ƒ at x = a.

• Normal distribution

A distribution of data shaped like the normal curve.

• Placebo

In an experimental study, an inactive treatment that is equivalent to the active treatment in every respect except for the factor about which an inference is to be made. Subjects in a blind experiment do not know if they have been given the active treatment or the placebo.

• 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

• Second-degree equation in two variables

Ax 2 + Bxy + Cy2 + Dx + Ey + F = 0, where A, B, and C are not all zero.

• Square matrix

A matrix whose number of rows equals the number of columns.

• Trichotomy property

For real numbers a and b, exactly one of the following is true: a < b, a = b , or a > b.

• Vertices of a hyperbola

The points where a hyperbola intersects the line containing its foci.

• Work

The product of a force applied to an object over a given distance W = ƒFƒ ƒAB!ƒ.

• Ymin

The y-value of the bottom of the viewing window.
