Key Calculus Terms and definitions covered in this textbook
• Arccotangent function

See Inverse cotangent function.

• Direction vector for a line

A vector in the direction of a line in three-dimensional space

• Empty set

A set with no elements

• 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.

• Horizontal asymptote

The line is a horizontal asymptote of the graph of a function ƒ if lim x:- q ƒ(x) = or lim x: q ƒ(x) = b

• Identity matrix

A square matrix with 1’s in the main diagonal and 0’s elsewhere, p. 534.

• Inverse cotangent function

The function y = cot-1 x

• Linear programming problem

A method of solving certain problems involving maximizing or minimizing a function of two variables (called an objective function) subject to restrictions (called constraints)

A measure that tells how widely distributed data are.

• Parametric equations

Equations of the form x = ƒ(t) and y = g(t) for all t in an interval I. The variable t is the parameter and I is the parameter interval.

• Projectile motion

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

• Projection of u onto v

The vector projv u = au # vƒvƒb2v

An angle in standard position whose terminal side lies on an axis.

• Quotient of functions

a ƒ g b(x) = ƒ(x) g(x) , g(x) ? 0

• Reflexive property of equality

a = a

• Solution of an equation or inequality

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

• Solve a triangle

To find one or more unknown sides or angles of a triangle

• Sum of an infinite series

See Convergence of a series

• Vertical stretch or shrink

See Stretch, Shrink.

• y-axis

Usually the vertical coordinate line in a Cartesian coordinate system with positive direction up, pp. 12, 629.
