Conditional probability
The probability of an event A given that an event B has already occurred

Convergence of a sequence
A sequence {an} converges to a if limn: q an = a

Elements of a matrix
See Matrix element.

Initial point
See Arrow.

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

Linear system
A system of linear equations

Multiplication principle of probability
If A and B are independent events, then P(A and B) = P(A) # P(B). If Adepends on B, then P(A and B) = P(AB) # P(B)

Negative association
A relationship between two variables in which higher values of one variable are generally associated with lower values of the other variable.

Normal curve
The graph of ƒ(x) = ex2/2

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

Parametric curve
The graph of parametric equations.

Perihelion
The closest point to the Sun in a planet’s orbit.

Probability function
A function P that assigns a real number to each outcome O in a sample space satisfying: 0 … P1O2 … 1, P12 = 0, and the sum of the probabilities of all outcomes is 1.

Quotient identities
tan ?= sin ?cos ?and cot ?= cos ? sin ?

Solution of a system in two variables
An ordered pair of real numbers that satisfies all of the equations or inequalities in the system

Solve algebraically
Use an algebraic method, including paper and pencil manipulation and obvious mental work, with no calculator or grapher use. When appropriate, the final exact solution may be approximated by a calculator

Standard form of a polar equation of a conic
r = ke 1 e cos ? or r = ke 1 e sin ? ,

Statistic
A number that measures a quantitative variable for a sample from a population.

Term of a polynomial (function)
