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}. |
