I was solving for the upper bound of a complicated probability distribution and I was able to use Mathematica to get a decimal approximation. I dropped that number into WolframAlpha to see if perhaps there was a closed-form solution.
This is one of the possibilities, alas I have no idea what script B refers to... I am not sure if this is even related to by probability density, at this point I want to know what it is just out of curiosity.
The pdf I was working on was (starting at x=1, ending at the aforementioned decimal):
