I have spent several days trying and failing to solve this problem. I am a teacher student of mine found it online. They asked for help solving it and initially I thought that there was a sign error because if so, I could easily solve it by substitution. However, the student maintains that it can be solved. I have tried so many things, I even resorted to using an online integral calculator which said there was no antiderivative. I am just so drained and demoralized, any help with this is appreciated.
