A
Asymptotes -- Straight lines that have the property of becoming and staying arbitrarily close to the curve as the distance from the origin increases to infinity. For example, the
x- axis is the only asymptote to the graph of sin(
x)/x.
B
Base -- the number that serves as a starting point for a logarithmic or other numerical system.
C
Change of Base Formula
Complex Numbers -- Numbers that have the form a + bi where a and b are real numbers and i satisfies the equation i2 = -1. Multiplication is denoted by ( a + bi )( c + di ) = ( ac - bd ) + ( ad + bc ) i , and addition is denoted by ( a + bi ) + ( c + di ) = ( a + c ) + ( b + d ) i .
D
DeMoivre's Theorem
E
Exponent -- The power to which a number or variable is raised (the exponent may be any real number).
F
Fundamental Theorem of Algebra
Focus (pl. foci) -- a point having the property that the distances from any point on a curve to it and to a fixed line have a constant ratio for all points on the curve.
G
H
Horizonatal Asymptote
I
Index
J
K
L
Logarithm -- The inverse of exponentiation; for example, alogax = x.
M
N
O
P
Polar Coordinates -- The coordinate system for the plane based on r , q , the distance from the origin and q , and the angle between the positive x- axis and the ray from the origin to the point.
Q
R
Rectangular Coordinates
S
T
U
V
Vector -- Quantity that has magnitude (length) and direction. It may be represented as a directed line segment.
W
X
Y
Z
