Exemple de sortie écran :

 Does lim x->oo [(2*x-3)/(2*x+3)]**x exist ?

 f(+1000.0) = 0.04979 
 f(+1500.0) = 0.04979 
 f(+2000.0) = 0.04979 
 f(+2500.0) = 0.04979 
 f(+3000.0) = 0.04979 
 f(+3500.0) = 0.04979 
 f(+4000.0) = 0.04979 
 f(+4500.0) = 0.04979 
 

 With the table we arrive at the following conjecture.

     lim x->oo [(2*x-3)/(2*x+3)]**x = exp(-6/2) = exp(-3) = 0.04979
