Addition property of inequality
If u < v , then u + w < v + w

Amplitude
See Sinusoid.

Bounded above
A function is bounded above if there is a number B such that ƒ(x) ? B for all x in the domain of ƒ.

Coefficient
The real number multiplied by the variable(s) in a polynomial term

Completing the square
A method of adding a constant to an expression in order to form a perfect square

Compound interest
Interest that becomes part of the investment

Equation
A statement of equality between two expressions.

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.

Inverse cotangent function
The function y = cot1 x

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.

Probability distribution
The collection of probabilities of outcomes in a sample space assigned by a probability function.

Probability function
A function P that assigns a real number to each outcome O in a sample space satisfying: 0 … P1O2 … 1, P12 = 0, and the sum of the probabilities of all outcomes is 1.

Pseudorandom numbers
Computergenerated numbers that can be used to approximate true randomness in scientific studies. Since they depend on iterative computer algorithms, they are not truly random

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

Random variable
A function that assigns realnumber values to the outcomes in a sample space.

Reflection across the xaxis
x, y and (x,y) are reflections of each other across the xaxis.

Resolving a vector
Finding the horizontal and vertical components of a vector.

Solve a system
To find all solutions of a system.

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

yintercept
A point that lies on both the graph and the yaxis.
