If any additional controlled variables were changing, it would be impossible to definitively determine the connection between the independent and dependent variables. Two hundred years later, the idea of infinitesimal calculus was developed, which led to the development of a “function”, in which an infinitesimal variation of a variable quantity causes a corresponding variation in another quantity, making the latter of a function of the former.
