How can the integral of exp (-1/x) be solved?

[jjmac]

Hi to everyone,

I am new in this site ( I hope this is the right place to ask my question).

Does anyone know how to solve the integral of: exp (-1/x)


I know that integral of exp(-x) = -exp(-x)+C but I have been trying to solve this for a while and I can not get the aswer.

I would appreciate any help.

Thanks

Where did you get that integral from? It's not a particularly easy one. Can you give us some context, perhaps also what you know about integrals?

It is not an elementary function, it can be written in terms of the exponential integral.
