E^n/n^3->(cosh(n)+sinh(n))/n^3 which has complex infinity as its limit as
n-> infinity

Use ExpToTrig and then take the limit.  Does this help??

I am trying to find the limit of the following expression : 

(E^n / n^3), n is growing to pos. infinity. But Mathematica 4.2 only
yield the expression in return! And it shipped with no comprehensive
doc, since it is a student version.

Any suggestions?
