Hi, I seem to be stumped with calculating this indefinite integral:
∫e^1/x−6x^2dx
I'm using integration by parts, but I can't find how to take the integral of e^1/x...how does it work?
Thank you, kind sirs!

Hi !
The integral of exp(1/x) cannot be expressed as a combination of a finite number of elementary functions. It's formal expression requires a special function, namely Ei(x).
integrate exp(1/x) - Wolfram|Alpha
Of course, it is possible to express the integral of exp(1/x) on the form of infinite series.
