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

Boundary
The set of points on the “edge” of a region

Cardioid
A limaçon whose polar equation is r = a ± a sin ?, or r = a ± a cos ?, where a > 0.

Center
The central point in a circle, ellipse, hyperbola, or sphere

Characteristic polynomial of a square matrix A
det(xIn  A), where A is an n x n matrix

Chord of a conic
A line segment with endpoints on the conic

Doubleangle identity
An identity involving a trigonometric function of 2u

Equilibrium price
See Equilibrium point.

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

Exponential growth function
Growth modeled by ƒ(x) = a ? b a > 0, b > 1 .

Feasible points
Points that satisfy the constraints in a linear programming problem.

Initial side of an angle
See Angle.

Linear factorization theorem
A polynomial ƒ(x) of degree n > 0 has the factorization ƒ(x) = a(x1  z1) 1x  i z 22 Á 1x  z n where the z1 are the zeros of ƒ

Mathematical model
A mathematical structure that approximates phenomena for the purpose of studying or predicting their behavior

Measure of an angle
The number of degrees or radians in an angle

Opposite
See Additive inverse of a real number and Additive inverse of a complex number.

Partial fractions
The process of expanding a fraction into a sum of fractions. The sum is called the partial fraction decomposition of the original fraction.

Pseudorandom numbers
Computergenerated numbers that can be used to approximate true randomness in scientific studies. Since they depend on iterative computer algorithms, they are not truly random

Reference triangle
For an angle ? in standard position, a reference triangle is a triangle formed by the terminal side of angle ?, the xaxis, and a perpendicular dropped from a point on the terminal side to the xaxis. The angle in a reference triangle at the origin is the reference angle

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