find n

plz tell me where u get this question.

for n = 200 the integral is ≈0.97

you make n slightly large say greater than 2000 it will be 1

so there are infinite n

No indefinite integral exists for this function

*I used wolfram|alpha

wolfram gives approx answers , you can only say that the value of the integral reaches 1 as ngrows , but you cant say it equals 1 infinitely many times , since it is not periodic .

My answer - The Golden Ratio .

It is discussed here -

However , the solution posted there is not a " solution " , rather an observation , as we cannot claim to have solved the equation fully .

I have been able to sketch a proof , but it is , as usual , way too complex . Kindly notify me if you want the solution .

have u solved the equation involving gamma functions ? or any other way...

please post the solution

i m very curious to see what you have done..
