Arithmetic Sequence
a sequence in which the difference of consecutive terms is constant
asymptote
a line that a graph approaches more and more closely
change of base formula
logb a=logd a/logd b
circle
shape consisting of all points in a plane that are at a given distance from a given point
combined variation
a situation where a variable depends on two (or more) other variables, and varies directly with some of them and varies inversely with others
common difference
the constant difference d between consecutive terms of an arithmetic sequence
common logarithm
a logarithm with base 10
common ratio
the constant ratio r between consecutive terms of a geometric sequence
completing the square
to add a term c to an expression of the form x^2+bx+c is a perfect square trinomial
complex conjugates
pairs of complex numbers of the forms a+bi and a-bi, where b≠0
complex fraction
a fraction that contains a fraction in its numerator or denominator
complex number
a number written in the form a+bi where a and b are real numbers
composition of functions
an operation that can be performed with two functions
compound inequalities
an inequality that combines two simple inequalities
conic section
a figure formed by the intersection of a plane and a right circular cone
consistent
a linear or nonlinear system of equations
constant of variation
the constant a in the inverse variation y=a/x, where a≠0
continuous relation
continuous in the usual sense and a composition of continuous relations is continuous
correlation coefficient
a number r from -1 to 1 that measures how well a line fits a set of data pairs (x,y)
dependant
the variable that depends on the value of some other number
dimensions of a matrix
the dimensions of a matrix with m rows and n columns are m x n
direct variation
simple relationship between two variables
discriminant
the expression b^2 -4ac in the quadratic formula
ellipse
a plane curve surrounding two focal points
