# This question is about integration with special function Dramatically challenging watch

1. Int from 0 to 1 xK^2(x)dx/square root(1-x^2) Let me post a specific picture
2. Let me see who can post a unbelievable result. I was astonished by this question.

What is your question? If you want the integral evaluated, you'd better tell people what K(x) is! Do you mean the generalized hyperfactorial function?
4. Hope you're not over-exaggerating the amazing-ness of the result like in the last thread tho
5. Wolfram gives numeric answer 8.47396694469461436, the inverse symbolic calculator suggests

5/4*Pi+7/3*ln(2)+8/3*ln(3)

1/2*ln(3)^(2/5)*exp(8/9*Pi)

but I confess neither seems terribly likely to me.

Much as I hate to say it, this is the kind of question you'd be better posting on https://math.stackexchange.com

I personally think that The amazing-ness in this question is exactly the result of calculation.

FWIW, I was assuming K = complete elliptic integral of first kind (seemed to tally with the term as well).

Yeah K(x) is exactly the complete elliptic integral of first kind.
