Hi Frank, in your expression there are symbols not defined. I'll try to define them in this attempt: In[1]:=Assuming[{r>0,0<s<1}, Limit[((1 + r)^t*(1 - s) + s)^(1/t) - 1, t ->Infinity]] Out[1]= r HTH, ~Scout~ "Frank Hechtner" <frank.hechtner at rub.de> news:eh79cr$dpb$1 at smc.vnet.net... > Hi, > > i?m in trouble with the calculation of limits. my expression is the > following > > ((1 + r)^t*(1 - s) + s)^(1/t) - 1, t -> ? > > as you see, the limit is r when x approaches ?. > > Unfortunately when using limit the output is > > Limit[((1 + r)^t*(1 - s) + s)^(1/t) - 1, t -> ?]. > > I dont see whats going wrong.
