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

Bias
A flaw in the design of a sampling process that systematically causes the sample to differ from the population with respect to the statistic being measured. Undercoverage bias results when the sample systematically excludes one or more segments of the population. Voluntary response bias results when a sample consists only of those who volunteer their responses. Response bias results when the sampling design intentionally or unintentionally influences the responses

Bounded
A function is bounded if there are numbers b and B such that b ? ƒ(x) ? B for all x in the domain of f.

Coefficient
The real number multiplied by the variable(s) in a polynomial term

Component form of a vector
If a vector’s representative in standard position has a terminal point (a,b) (or (a, b, c)) , then (a,b) (or (a, b, c)) is the component form of the vector, and a and b are the horizontal and vertical components of the vector (or a, b, and c are the x, y, and zcomponents of the vector, respectively)

Cone
See Right circular cone.

Control
The principle of experimental design that makes it possible to rule out other factors when making inferences about a particular explanatory variable

Directed angle
See Polar coordinates.

Ellipsoid of revolution
A surface generated by rotating an ellipse about its major axis

Graph of an equation in x and y
The set of all points in the coordinate plane corresponding to the pairs x, y that are solutions of the equation.

Horizontal shrink or stretch
See Shrink, stretch.

Inductive step
See Mathematical induction.

Intercepted arc
Arc of a circle between the initial side and terminal side of a central angle.

Obtuse triangle
A triangle in which one angle is greater than 90°.

Parametric curve
The graph of parametric equations.

Pointslope form (of a line)
y  y1 = m1x  x 12.

Sequence of partial sums
The sequence {Sn} , where Sn is the nth partial sum of the series, that is, the sum of the first n terms of the series.

Summation notation
The series a nk=1ak, where n is a natural number ( or ?) is in summation notation and is read "the sum of ak from k = 1 to n(or infinity).” k is the index of summation, and ak is the kth term of the series

Supply curve
p = ƒ(x), where x represents production and p represents price

Trichotomy property
For real numbers a and b, exactly one of the following is true: a < b, a = b , or a > b.
