Combination
An arrangement of elements of a set, in which order is not important

Compounded annually
See Compounded k times per year.

Definite integral
The definite integral of the function ƒ over [a,b] is Lbaƒ(x) dx = limn: q ani=1 ƒ(xi) ¢x provided the limit of the Riemann sums exists

Divergence
A sequence or series diverges if it does not converge

Expanded form of a series
A series written explicitly as a sum of terms (not in summation notation).

Invertible linear system
A system of n linear equations in n variables whose coefficient matrix has a nonzero determinant.

Limit at infinity
limx: qƒ1x2 = L means that ƒ1x2 gets arbitrarily close to L as x gets arbitrarily large; lim x: q ƒ1x2 means that gets arbitrarily close to L as gets arbitrarily large

Multiplication property of inequality

y = mx + b

Solution of an equation or inequality
A value of the variable (or values of the variables) for which the equation or inequality is true

Standard unit vectors
In the plane i = <1, 0> and j = <0,1>; in space i = <1,0,0>, j = <0,1,0> k = <0,0,1>
