arithmetic sequence
An arithmetic sequence is a sequence where each term increases by adding/subtracting some constant k.
asymptote
a line that continually approaches a given curve but does not meet it at any finite distance.
change of base formula
logb(a)=logx(a)/logx)a)
circle
a round plane figure
combined variation
describes 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 between consecutiveterms of an arithmetic sequence
common logarithim
a logorithim eith aa base of 10
common ratio
the constant ratio between consecutive terms of a geometric sequence
completing the square
method used to solve a quadratic equation by changing the form of the equation so that the left side is a perfect square trinomial
complex conjugates
Each of two complex numbers having their real parts identical and their imaginary parts of equal magnitude but opposite sign
complex fraction
fraction in which the denominator and numerator or both contain fractions
complex number
a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a symbol called the imaginary unit,
composition of function
an operation that takes two functions f and g and produces a function h such that h(x) = g(f(x)
compound inequality
a sentence with two inequality statements joined either by the word “or” or by the word “and.”
conic section
a curve obtained as the intersection of the surface of a cone with a plane.
consistent
unchanging in nature, standard, or effect over time
constant of variation
a direct variation is the constant (unchanged) ratio of two variable quantities
continuous relation
a function that can take on any number within a certain interval
correlation coefficient
are used to measure how strong a relationship is between two variables
dependent
contingent on or determined by.
dimensions of a matrix
The dimensions of a matrix are the number of rows by the number of columns
direct variation
Direct variation describes a simple relationship between two variables
discriminant
part of the quadratic formula underneath the square root symbol: b²-4ac
ellipse
the set of all points on a plane whose distance from two fixed points F and G add up to a constant
end behavior
describes the trend of the graph if we look to the right end of the x x xx-axis
exponential equation
a function of the form
where b is a positive real number, and the argument x occurs as an exponent
extraneous solution
a root of a transformed equation that is not a root of the original equation
extrema
the maximum or minimum value of a function
factor theorem
used when factoring polynomials
finite sequence
a list of terms in a specific order
