calculus - How do I solve limxtoinftyx(e(1/x)1) without L'Hopital?



I don't have experience with L'Hopital Rule nor series and thats what most solution are, is there is other method can be used to solve that limit? i thought about trying to use first principle of derivative but i dont know where to begin. i need some help to guide me to the right direction.


Answer



This is precisely limx+exp(1x)11x=limu0+exp(u)1u




Does that remind you of some derivative?
