Arrow
The notation PQ denoting the directed line segment with initial point P and terminal point Q.

Complex plane
A coordinate plane used to represent the complex numbers. The xaxis of the complex plane is called the real axis and the yaxis is the imaginary axis

Composition of functions
(f ? g) (x) = f (g(x))

Constant function (on an interval)
ƒ(x 1) = ƒ(x 2) x for any x1 and x2 (in the interval)

De Moivre’s theorem
(r(cos ? + i sin ?))n = r n (cos n? + i sin n?)

Division algorithm for polynomials
Given ƒ(x), d(x) ? 0 there are unique polynomials q1x (quotient) and r1x(remainder) ƒ1x2 = d1x2q1x2 + r1x2 with with either r1x2 = 0 or degree of r(x) 6 degree of d1x2

Ellipse
The set of all points in the plane such that the sum of the distances from a pair of fixed points (the foci) is a constant

An equation that can be written in the form.

Identity matrix
A square matrix with 1’s in the main diagonal and 0’s elsewhere, p. 534.

Index of summation
See Summation notation.

Minute
Angle measure equal to 1/60 of a degree.

Objective function
See Linear programming problem.

Product of complex numbers
(a + bi)(c + di) = (ac  bd) + (ad + bc)i

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.

Semiperimeter of a triangle
Onehalf of the sum of the lengths of the sides of a triangle.

Solution of an equation or inequality
A value of the variable (or values of the variables) for which the equation or inequality is true

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

Variation
See Power function.

Vertex of a cone
