Addition principle of probability.
P(A or B) = P(A) + P(B)  P(A and B). If A and B are mutually exclusive events, then P(A or B) = P(A) + P(B)

Augmented matrix
A matrix that represents a system of equations.

Bounded
A function is bounded if there are numbers b and B such that b ? ƒ(x) ? B for all x in the domain of f.

Combinatorics
A branch of mathematics related to determining the number of elements of a set or the number of ways objects can be arranged or combined

Continuous function
A function that is continuous on its entire domain

Inverse cosine function
The function y = cos1 x

Inverse of a matrix
The inverse of a square matrix A, if it exists, is a matrix B, such that AB = BA = I , where I is an identity matrix.

Linear regression equation
Equation of a linear regression line

Lower bound of f
Any number b for which b < ƒ(x) for all x in the domain of ƒ

Opens upward or downward
A parabola y = ax 2 + bx + c opens upward if a > 0 and opens downward if a < 0.

Position vector of the point (a, b)
The vector <a,b>.

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

Proportional
See Power function

Random behavior
Behavior that is determined only by the laws of probability.

Spiral of Archimedes
The graph of the polar curve.

Stretch of factor c
A transformation of a graph obtained by multiplying all the xcoordinates (horizontal stretch) by the constant 1/c, or all of the ycoordinates (vertical stretch) of the points by a constant c, c, > 1.

Sum of an infinite series
See Convergence of a series

Symmetric difference quotient of ƒ at a
ƒ(x + h)  ƒ(x  h) 2h

Third quartile
See Quartile.
