Implicit Function

A function which is not defined explicitly, but rather is defined in terms of an algebraic relationship (which can not, in general, be "solved" for the function in question). For example, the eccentric anomaly E of a body orbiting on an ellipse with eccentricity e is defined implicitly in terms of the mean anomaly M by Kepler's equation
