Algebraic model
An equation that relates variable quantities associated with phenomena being studied

Chord of a conic
A line segment with endpoints on the conic

Coordinate(s) of a point
The number associated with a point on a number line, or the ordered pair associated with a point in the Cartesian coordinate plane, or the ordered triple associated with a point in the Cartesian threedimensional space

Differentiable at x = a
ƒ'(a) exists

Directed angle
See Polar coordinates.

Empty set
A set with no elements

Fivenumber summary
The minimum, first quartile, median, third quartile, and maximum of a data set.

Implied domain
The domain of a function’s algebraic expression.

Initial side of an angle
See Angle.

Inverse cosine function
The function y = cos1 x

Law of sines
sin A a = sin B b = sin C c

Parameter interval
See Parametric equations.

Righthand limit of ƒ at x a
The limit of ƒ as x approaches a from the right.

Slopeintercept form (of a line)
y = mx + b

Sum of functions
(ƒ + g)(x) = ƒ(x) + g(x)

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
