Key Calculus Terms and definitions covered in this textbook
• Coefficient

The real number multiplied by the variable(s) in a polynomial term

• Combination

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

• Combinations of n objects taken r at a time

There are nCr = n! r!1n - r2! such combinations,

• Convenience sample

A sample that sacrifices randomness for convenience

• Direction angle of a vector

The angle that the vector makes with the positive x-axis

• Equally likely outcomes

Outcomes of an experiment that have the same probability of occurring.

• Exponential decay function

Decay modeled by ƒ(x) = a ? bx, a > 0 with 0 < b < 1.

• Graph of a polar equation

The set of all points in the polar coordinate system corresponding to the ordered pairs (r,?) that are solutions of the polar equation.

• Index

• Lower bound of f

Any number b for which b < ƒ(x) for all x in the domain of ƒ

• Negative angle

Angle generated by clockwise rotation.

• Order of magnitude (of n)

log n.

• Polar coordinates

The numbers (r, ?) that determine a point’s location in a polar coordinate system. The number r is the directed distance and ? is the directed angle

• Polynomial in x

An expression that can be written in the form an x n + an-1x n-1 + Á + a1x + a0, where n is a nonnegative integer, the coefficients are real numbers, and an ? 0. The degree of the polynomial is n, the leading coefficient is an, the leading term is anxn, and the constant term is a0. (The number 0 is the zero polynomial)

• Probability simulation

A numerical simulation of a probability experiment in which assigned numbers appear with the same probabilities as the outcomes of the experiment.

• Real axis

See Complex plane.

• Sine

The function y = sin x.

• Solution of a system in two variables

An ordered pair of real numbers that satisfies all of the equations or inequalities in the system

• Standard form of a complex number

a + bi, where a and b are real numbers

• Weighted mean

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.
