Key Calculus Terms and definitions covered in this textbook
• Algebraic model

An equation that relates variable quantities associated with phenomena being studied

• Center

The central point in a circle, ellipse, hyperbola, or sphere

• Cofunction identity

An identity that relates the sine, secant, or tangent to the cosine, cosecant, or cotangent, respectively

• Combination

An arrangement of elements of a set, in which order is not important

• Commutative properties

a + b = b + a ab = ba

• Correlation coefficient

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

• De Moivre’s theorem

(r(cos ? + i sin ?))n = r n (cos n? + i sin n?)

• Endpoint of an interval

A real number that represents one “end” of an interval.

• Finite sequence

A function whose domain is the first n positive integers for some fixed integer n.

• Frequency (in statistics)

The number of individuals or observations with a certain characteristic.

• Horizontal shrink or stretch

See Shrink, stretch.

• Mathematical model

A mathematical structure that approximates phenomena for the purpose of studying or predicting their behavior

• Measure of center

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

• Observational study

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.

• Opposite

See Additive inverse of a real number and Additive inverse of a complex number.

• Plane in Cartesian space

The graph of Ax + By + Cz + D = 0, where A, B, and C are not all zero.

• Principal nth root

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.

• Solution of an equation or inequality

A value of the variable (or values of the variables) for which the equation or inequality is true

• Vertical stretch or shrink

See Stretch, Shrink.

• Ymin

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