Closed Form of a really difficult Integral

I became very interested in the closed form for the following Integral:0π21(1+x2)(1+tanx)dx\int_{0}^{\Large\frac{\pi}{2}}\frac{1}{(1+x^2)(1+\tan x)}\,\mathrm dx No known exactexact Closed Form for this Integral exists so far (well not to my knowledge at least). However, I thought I would post it as members of the community might be interested in finding its Closed Form. Happy solving!

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

  • Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
  • Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
  • Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
  • Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

Please don't mass @mention too many people at once. I'm fine with you @mentioning me but but please keep it to a maximum of 4 people at once. Those 4 will feel more inclined to respond in that case.

have you tried this

Yeah, but that's an approximateapproximate form. By the way, I hope I'm not breaking a rule by hoping to get people interested in finding and exact Closed Form. If I am, I'll delete it immediately.

@Ishan Dasgupta Samarendra The closed form of the above integral can only be found by an excellent approximation, as said by tunk-fey araiawan.i provided the link for furthur details and assumption about the problem, as soon as anyone comes up with a solution to your doubt,i will immediately remove the link.

and no , dont delete the note, i am okay with it.

Could you please remove the reference to that problem? This is because some people might use what will perhaps appear subsequently in a manner which would not do justice to that problem.
