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

A combination of variables and constants involving addition, subtraction, multiplication, division, powers, and roots

• Arithmetic sequence

A sequence {an} in which an = an-1 + d for every integer n ? 2 . The number d is the common difference.

• Associative properties

a + (b + c) = (a + b) + c, a(bc) = (ab)c.

• Augmented matrix

A matrix that represents a system of equations.

• Cosine

The function y = cos x

• Double-blind experiment

A blind experiment in which the researcher gathering data from the subjects is not told which subjects have received which treatment

• Five-number summary

The minimum, first quartile, median, third quartile, and maximum of a data set.

• Frequency (in statistics)

The number of individuals or observations with a certain characteristic.

• Inequality

A statement that compares two quantities using an inequality symbol

• Inverse cosine function

The function y = cos-1 x

• Inverse cotangent function

The function y = cot-1 x

• Lower bound test for real zeros

A test for finding a lower bound for the real zeros of a polynomial

• Nautical mile

Length of 1 minute of arc along the Earth’s equator.

• 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.

• Random numbers

Numbers that can be used by researchers to simulate randomness in scientific studies (they are usually obtained from lengthy tables of decimal digits that have been generated by verifiably random natural phenomena).

• Rational zeros theorem

A procedure for finding the possible rational zeros of a polynomial.

• Repeated zeros

Zeros of multiplicity ? 2 (see Multiplicity).

• Scientific notation

A positive number written as c x 10m, where 1 ? c < 10 and m is an integer.

• y-intercept

A point that lies on both the graph and the y-axis.

• Yscl

The scale of the tick marks on the y-axis in a viewing window.
