## Definition of Variable

Variable
Variable Va"ri*a*ble, n. 1. That which is variable; that which varies, or is subject to change. 2. (Math.) A quantity which may increase or decrease; a quantity which admits of an infinite number of values in the same expression; a variable quantity; as, in the equation x^2 - y^2 = R^2, x and y are variables. 3. (Naut.) (a) A shifting wind, or one that varies in force. (b) pl. Those parts of the sea where a steady wind is not expected, especially the parts between the trade-wind belts. Independent variable (Math.), that one of two or more variables, connected with each other in any way whatever, to which changes are supposed to be given at will. Thus, in the equation x^2 - y^2 = R^2, if arbitrary changes are supposed to be given to x, then x is the independent variable, and y is called a function of x. There may be two or more independent variables in an equation or problem. Cf. Dependent variable, under Dependent.
