Una función y(x) se llama implícita cuando está definida de la forma F(x, y) = 0 en lugar de la habitual. Por ejemplo, puede probarse que la siguiente ecuación define una función implícita en cierta región de entre las variables x e y:

In mathematics, an implicit equation is a relation of the form , where is a function of several variables (often a polynomial). For example, the implicit equation of the unit circle is . An implicit function is a function that is defined implicitly by an implicit equation, by associating one of the variables (the value) with the others (the arguments). Thus, an implicit function for in the context of the unit circle is defined implicitly by . This implicit equation defines as a function of only if and one considers only non-negative (or non-positive) values for the values of the function. The implicit function theorem provides conditions under which a relation defines an implicit function.
