Two days ago a friend of mine shared with me a question stating that I couldn't solve that question and neither will anyone on Brilliant .

Darn him ! But he turned out to be partially correct , since I wasn't able to solve it and hence I am appealing to all the Brilliant minds out here to lend me your hand in solving the following question :

\[\displaystyle \huge \sum_{r=1}^{\infty} \sqrt{ \int_{0}^{\frac{\pi}{2}} \left ( 5+ \Gamma \left ( \dfrac{2}{2+x^{2r}} \right ) \right ) dx}\]

P.S. I tried using the Weirerstrass form and stuff , but was unsuccessful . I even posted this question in 3 communities in Google Plus , ends up that they got scared after seeing this question !

Best of Luck !!!

Ok, sorry guys !! I didn't do the convergence test first !! I always forget to do itLog in to reply

What's the claim that it converges? – Kartik Sharma · 2 years ago

@Azhaghu Roopesh M , are you sure this question is solvable? Take it from a guy with experience, I once spent a whole day trying to prove Fermat's last theorem after my friend told me that I will never be able to solve it. Of course, I got to know that it was way out of my league the next day. – Raghav Vaidyanathan · 2 years ago

Yes, sorry abt that ! I didn't do the convergence testLog in to reply

Sorry Azhaghu i only know the basics of calculus.And its would be very hard for me to figure out this question...And I think there is a small typo in your mentioning...probably you mentioned Karthik instead of Kartik(I think)..ThanksLog in to reply
