artesian coordinate system
An association between the points in a plane and ordered pairs of real numbers; or an association between the points in threedimensional space and ordered triples of real numbers

Axis of symmetry
See Line of symmetry.

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

Circle
A set of points in a plane equally distant from a fixed point called the center

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

Compounded annually
See Compounded k times per year.

Explicitly defined sequence
A sequence in which the kth term is given as a function of k.

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

Heron’s formula
The area of ¢ABC with semiperimeter s is given by 2s1s  a21s  b21s  c2.

Intermediate Value Theorem
If ƒ is a polynomial function and a < b , then ƒ assumes every value between ƒ(a) and ƒ(b).

Main diagonal
The diagonal from the top left to the bottom right of a square matrix

Maximum rvalue
The value of r at the point on the graph of a polar equation that has the maximum distance from the pole

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

Projection of u onto v
The vector projv u = au # vƒvƒb2v

Second quartile
See Quartile.

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
