A number that must be multiplied times itself three times to equal a given number.
A method for solving a linear system of equations using determinants.
An infinite series for which the sequence of partial sums converges.
A sequence with a limit that is a real number. For example, the sequence 2. 1, 2. 01, 2. 001, 2. 0001, . . . has limit 2, so the sequence converges to 2.

A function of the form y = constant or f(x) = constant, such as y = –2.
A measured quantity that does not change, or that stays the same under particular conditions. A constant is, by convention, often entered in equations as a letter symbol.
