Resumen

VAZQUEZ-LEAL, H.  y  BOUBAKER, K.. Approximate solutions for the model of evolution of cocaine consumption in Spain using HPM and BPEs methods. Nova scientia [online]. 2014, vol.6, n.12, pp.171-189. ISSN 2007-0705.

In this paper, two methods are applied to a system of nonlinear differential equations that models the evolution of consumption of cocaine in Spain. Theoretical considerations have been detailed as guides to demonstrate the ability and reliability of both methods. Comparing results obtained by employing these techniques revealed that they are effective and convenient.

Palabras llave : Cocaine consumption; nonlinear differential equations; mathematical models.
