    Integral
In summary, the conversation discusses the integral \int_0^1\exp[ax-b/(x)]x^{-3/2}dx, where 0<x<1, a>0, and b>0. The speaker mentions that there is no closed form for this integral and it goes to infinity for certain values of a and b. They then ask if it can be expressed using special functions, such as hypergeometric functions, and mention that they were unable to find any similar forms in math handbooks. Some people suggested using the residual theorem, which the speaker is not familiar with. They also mention trying a Monte Carlo simulation, which resulted in a nice curve shape that they believe can be expressed using special functions.

\int_0^1\exp[ax-b/(x)]x^{-3/2}dx, where 0<x<1, a>0, b>0.
I know there is no closed form, and it goes to infinity for some value of a and b, but is it able to expresse it by some special functions, like hypergeometric functions?
I checked the math handbooks, could not find any similar forms. Some people suggested using residual theorem which I am not familar with. I tried Monte Carlo simulation and it has nice curve shape that I feel can be expressed by some special functions.

Thanks very much if anyone can help!

Sorry, when I say nice curve shaple, I mean as a function of b given certain a values.
