I need a proof that lim(1+1/x)^x=e.

We defined that e=lim(1+1/n)^n and I need to prove that it's same for x (real number).

Thanks.

## Re: lim (1+1/x)^x

The question seems trivial, as:

Is the exact same statement as:

Just let n = x.

Though, this also seems trivial.. Even if they were integers or natural numbers, it would still approach the value of 'e' as the limit went to infinity.

Have you done the proof for the 'n' in class?
