The extrinsic method (see document on Vixra.org) is another mathematical method allowing to get answers when the so-called (E) question is asked.
In opposition with the intrinsic method, the procedure brings a complete result; I mean: a main part and a residual part.
Its disadvantages: the result is an approximation and the procedure itself must be counterchecked with a logical test. In fact, the (E) question receives reasonable answers when both methods are confronted. The confrontation realizes a calibration (see document on Vixra.org).
