Jerry, It seems that in some cases Assuming beforehand is better than Simplifying afterwards. Assuming[a > 0, Limit[Exp[-a t], t -> Infinity]] 0 Assuming[a < 0, Limit[Exp[-a t], t -> Infinity]] Infinity David Park djmp at earthlink.net http://home.earthlink.net/~djmp/ From: Blimbaum, Jerry CIV NSWC PC [mailto:jerry.blimbaum at navy.mil] To: mathgroup at smc.vnet.net Why do these give no output? Simplify[Limit[Exp[-a t],t->Infinity],a>0] and same for Simplify[Limit[Exp[a t],t->Infinity],a<0] thanks... Jerry Blimbaum
