Amplitude
See Sinusoid.

Binomial probability
In an experiment with two possible outcomes, the probability of one outcome occurring k times in n independent trials is P1E2 = n!k!1n  k2!pk11  p) nk where p is the probability of the outcome occurring once

Blocking
A feature of some experimental designs that controls for potential differences between subject groups by applying treatments randomly within homogeneous blocks of subjects

Branches
The two separate curves that make up a hyperbola

Common difference
See Arithmetic sequence.

Conic section (or conic)
A curve obtained by intersecting a doublenapped right circular cone with a plane

Cosecant
The function y = csc x

Extraneous solution
Any solution of the resulting equation that is not a solution of the original equation.

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.

Minor axis
The perpendicular bisector of the major axis of an ellipse with endpoints on the ellipse.

Onetoone rule of exponents
x = y if and only if bx = by.

Ordinary annuity
An annuity in which deposits are made at the same time interest is posted.

Outcomes
The various possible results of an experiment.

Reflexive property of equality
a = a

Row echelon form
A matrix in which rows consisting of all 0’s occur only at the bottom of the matrix, the first nonzero entry in any row with nonzero entries is 1, and the leading 1’s move to the right as we move down the rows.

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

Sine
The function y = sin x.

Symmetric property of equality
If a = b, then b = a

Terminal side of an angle
See Angle.

Transitive property
