Confounding variable
A third variable that affects either of two variables being studied, making inferences about causation unreliable

Direction angle of a vector
The angle that the vector makes with the positive xaxis

End behavior
The behavior of a graph of a function as.

equation of a quadratic function
ƒ(x) = ax 2 + bx + c(a ? 0)

Finite sequence
A function whose domain is the first n positive integers for some fixed integer n.

Fundamental
Theorem of Algebra A polynomial function of degree has n complex zeros (counting multiplicity).

Graph of a polar equation
The set of all points in the polar coordinate system corresponding to the ordered pairs (r,?) that are solutions of the polar equation.

Inverse properties
a + 1a2 = 0, a # 1a

Linear function
A function that can be written in the form ƒ(x) = mx + b, where and b are real numbers

Local extremum
A local maximum or a local minimum

Partial fractions
The process of expanding a fraction into a sum of fractions. The sum is called the partial fraction decomposition of the original fraction.

Principle of mathematical induction
A principle related to mathematical induction.

Radian measure
The measure of an angle in radians, or, for a central angle, the ratio of the length of the intercepted arc tothe radius of the circle.

Rational zeros
Zeros of a function that are rational numbers.

Removable discontinuity at x = a
lim x:a ƒ(x) = limx:a+ ƒ(x) but either the common limit is not equal ƒ(a) to ƒ(a) or is not defined

Richter scale
A logarithmic scale used in measuring the intensity of an earthquake.

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

Sine
The function y = sin x.
