You look after Apart : In[1]:= Apart[(8*s + 10)/((s + 1)*(s + 3)^2)] Out[1]= -(1/(2*(s + 3))) + 7/(s + 3)^2 + 1/(2*(s + 1)) Looks like you want to use the Inverse Laplace Transform? In[3]:= InverseLaplaceTransform[(8*s + 10)/((s + 1)*(s + 3)^2), s, t] Out[3]= ((1/2)*(14*t + E^(2*t) - 1))/E^(3*t) Regards F.Jaccard -----Message d'origine----- De : Jack [mailto:ajack at remove.com] Envoyé : mardi, 7. décembre 2004 10:10 À : mathgroup at smc.vnet.net Objet : [mg52663] Partial fraction command Hello, Is there any built-in command for partial fraction in Mathematica? eg (8s + 10)/(s+1)(s+3)^2 = a1/(s+1) + a2/(s+3)^2 +a3/(s+3) to get a1,a2,and a3.
