\epsfig{file=van_der_pol_trap_cos.eps,width=400pt}

Description

The Van Der Pol's Equation is written with the equation :

$\displaystyle x+\left(x^{2}-1\right)\dot{x}+x=0
$

It is fully described by the following system of state equation :

$\displaystyle \dot{x}\,=\,y
$

$\displaystyle \dot{y}\,=\,\left(1-x^{2}\right)y-x
$
