Key Calculus Terms and definitions covered in this textbook
• Argument of a complex number

The argument of a + bi is the direction angle of the vector {a,b}.

• Bounded below

A function is bounded below if there is a number b such that b ? ƒ(x) for all x in the domain of f.

• Categorical variable

In statistics, a nonnumerical variable such as gender or hair color. Numerical variables like zip codes, in which the numbers have no quantitative significance, are also considered to be categorical.

• Index of summation

See Summation notation.

• Law of cosines

a2 = b2 + c2 - 2bc cos A, b2 = a2 + c2 - 2ac cos B, c2 = a2 + b2 - 2ab cos C

• Length of an arrow

See Magnitude of an arrow.

• Linear regression equation

Equation of a linear regression line

• Outcomes

The various possible results of an experiment.

• Parameter interval

See Parametric equations.

• Positive numbers

Real numbers shown to the right of the origin on a number line.

• Reflection

Two points that are symmetric with respect to a lineor a point.

• Remainder polynomial

See Division algorithm for polynomials.

• Resistant measure

A statistical measure that does not change much in response to outliers.

• Solution of a system in two variables

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

• Solve an equation or inequality

To find all solutions of the equation or inequality

• Terminal side of an angle

See Angle.

• Trigonometric form of a complex number

r(cos ? + i sin ?)

• Union of two sets A and B

The set of all elements that belong to A or B or both.

• xz-plane

The points x, 0, z in Cartesian space.

• Zoom out

A procedure of a graphing utility used to view more of the coordinate plane (used, for example, to find theend behavior of a function).
