WebThe term "ordinary" is used in contrast with the term partial differential equation, which may be with respect to more than one independent variable. Linear differential equations, which have solutions that can be added and multiplied by coefficients, are well-defined and understood, and exact closed-form solutions are obtained. WebMost commonly, the independent variable is "x," (though others, such as t for time, are used as well) as in the equation y = x + 5 or in function notation: f (x) = x + 5 In the above, x is the independent variable because it is the variable that we control. Depending on what value of x is plugged into the function, f (x) (or y) changes.
