Key Calculus Terms and definitions covered in this textbook
• Annual percentage rate (APR)

The annual interest rate

• Associative properties

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

• Constant function (on an interval)

ƒ(x 1) = ƒ(x 2) x for any x1 and x2 (in the interval)

• Dependent variable

Variable representing the range value of a function (usually y)

• Directed angle

See Polar coordinates.

• Graph of a function ƒ

The set of all points in the coordinate plane corresponding to the pairs (x, ƒ(x)) for x in the domain of ƒ.

• Horizontal translation

A shift of a graph to the left or right.

• Integers

The numbers . . ., -3, -2, -1, 0,1,2,...2

• kth term of a sequence

The kth expression in the sequence

• Law of sines

sin A a = sin B b = sin C c

See Polynomial function in x

• LRAM

A Riemann sum approximation of the area under a curve ƒ(x) from x = a to x = b using x1 as the left-hand endpoint of each subinterval

• Number line graph of a linear inequality

The graph of the solutions of a linear inequality (in x) on a number line

• Placebo

In an experimental study, an inactive treatment that is equivalent to the active treatment in every respect except for the factor about which an inference is to be made. Subjects in a blind experiment do not know if they have been given the active treatment or the placebo.

• Projectile motion

The movement of an object that is subject only to the force of gravity

• Right circular cone

The surface created when a line is rotated about a second line that intersects but is not perpendicular to the first line.

• Sample survey

A process for gathering data from a subset of a population, usually through direct questioning.
