Additive identity for the complex numbers
0 + 0i is the complex number zero

Angle
Union of two rays with a common endpoint (the vertex). The beginning ray (the initial side) can be rotated about its endpoint to obtain the final position (the terminal side)

Binomial
A polynomial with exactly two terms

Central angle
An angle whose vertex is the center of a circle

Coefficient of determination
The number r2 or R2 that measures how well a regression curve fits the data

Constraints
See Linear programming problem.

Direction of an arrow
The angle the arrow makes with the positive xaxis

Elementary row operations
The following three row operations: Multiply all elements of a row by a nonzero constant; interchange two rows; and add a multiple of one row to another row

Horizontal Line Test
A test for determining whether the inverse of a relation is a function.

Inductive step
See Mathematical induction.

Measure of spread
A measure that tells how widely distributed data are.

Modified boxplot
A boxplot with the outliers removed.

nth root of a complex number z
A complex number v such that vn = z

Opens upward or downward
A parabola y = ax 2 + bx + c opens upward if a > 0 and opens downward if a < 0.

Partial sums
See Sequence of partial sums.

Perpendicular lines
Two lines that are at right angles to each other

Radicand
See Radical.

Randomization
The principle of experimental design that makes it possible to use the laws of probability when making inferences.

Standard position (angle)
An angle positioned on a rectangular coordinate system with its vertex at the origin and its initial side on the positive xaxis

Sum identity
An identity involving a trigonometric function of u + v
