Arcsecant function
See Inverse secant function.

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)

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

Cosecant
The function y = csc x

Directed line segment
See Arrow.

Direction vector for a line
A vector in the direction of a line in threedimensional space

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.

Instantaneous rate of change
See Derivative at x = a.

Line of symmetry
A line over which a graph is the mirror image of itself

Local maximum
A value ƒ(c) is a local maximum of ƒ if there is an open interval I containing c such that ƒ(x) < ƒ(c) for all values of x in I

Normal distribution
A distribution of data shaped like the normal curve.

Placebo
In an experimental study, an inactive treatment that is equivalent to the active treatment in every respect except for the factor about which an inference is to be made. Subjects in a blind experiment do not know if they have been given the active treatment or the placebo.

Radius
The distance from a point on a circle (or a sphere) to the center of the circle (or the sphere).

Rose curve
A graph of a polar equation or r = a cos nu.

Solve by elimination or substitution
Methods for solving systems of linear equations.

Transformation
A function that maps real numbers to real numbers.

Upper bound for real zeros
A number d is an upper bound for the set of real zeros of ƒ if ƒ(x) ? 0 whenever x > d.

xintercept
A point that lies on both the graph and the xaxis,.

Zero factorial
See n factorial.
