# Independent Variable

From ExoDictionary

**Independent Variable**

Any of those variables of a problem, chosen according to convenience, which may arbitrarily be specified, and which then determine the other or dependent variables of the problem.

*The independent variables are often called the coordinates, particularly in problems involving motion in space. Dependent and independent variables can be interchanges, e.g., height and pressure. *
