# A beautiful calculus problem 1

Somebody please provide the solution for this integral. Thanks a lot for the help. $\int { [\ln { ({ e }^{ { x }^{ 2 } } } +1)\quad +\quad 2\{ \frac { { e }^{ { x }^{ 2 } }(2{ x }^{ 2 }-1)-1 }{ ({ e }^{ { x }^{ 2 } }+1)^{ 2 } } \} ]dx }$

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.

What makes you think that there is a "nice" answer to this integral?

Or better yet, where did you find this integral?

What makes them "beautiful"? They all appear to be randomly constructed.

It's easy to see that Question 1 has a closed form via a simple substitution of y=x^pi + 7, but that doesn't make the integral beautiful.

Care to say anything about the other 4 questions?

I don't find that reason good enough to undermine their beauty.

Can you explain what you have tried? What makes you think there is a beautiful solution to this problem?

Its not the solution but the problem that's beautiful.
