- In differential calculus, a Forcing function (differential equations)Forcing function (differential equations)In a system of differential equations used to describe a time-dependent process, a forcing function is a function that appears in the equations and is only a function of time, not of any of the other variables. In effect, it is a constant for each value of t....
