Key Calculus Terms and definitions covered in this textbook
• Absolute value of a vector

See Magnitude of a vector.

• 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

• Convergence of a sequence

A sequence {an} converges to a if limn: q an = a

• Cosine

The function y = cos x

• Derivative of ƒ

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

• Elements of a matrix

See Matrix element.

• Ellipsoid of revolution

A surface generated by rotating an ellipse about its major axis

• Factoring (a polynomial)

Writing a polynomial as a product of two or more polynomial factors.

• Graphical model

A visible representation of a numerical or algebraic model.

• Imaginary unit

The complex number.

• Irrational zeros

Zeros of a function that are irrational numbers.

• Length of an arrow

See Magnitude of an arrow.

• Limit at infinity

limx: qƒ1x2 = L means that ƒ1x2 gets arbitrarily close to L as x gets arbitrarily large; lim x:- q ƒ1x2 means that gets arbitrarily close to L as gets arbitrarily large

• Probability function

A function P that assigns a real number to each outcome O in a sample space satisfying: 0 … P1O2 … 1, P12 = 0, and the sum of the probabilities of all outcomes is 1.

• Rectangular coordinate system

See Cartesian coordinate system.

• Right-hand limit of ƒ at x a

The limit of ƒ as x approaches a from the right.

• Standard deviation

A measure of how a data set is spread

• Symmetric difference quotient of ƒ at a

ƒ(x + h) - ƒ(x - h) 2h

• Variation

See Power function.

• Zero factorial

See n factorial.
