This is purely an observational thread, although you may choose to answer them anyway.

Post the most evil integrals you -have ever/happen to- come across in your mathematical endeavours.

And optionally, make a few observational comments on the integral, and any attempted evaluations of it.

My comment (long ago):

It is, at minimum, expressible using the real and imaginary parts of the 9th, 18th, and 36th roots of unity, and is extremely horrible, even if it does have a closed form primitive.

The similar integral



is completely trivial
