This is not a homework problem but something I saw on an another forum. Though the actual problem doesn't require the integral but I am interested to know if it possible to evaluate it.

The indefinite integral cannot be found in terms of elementary functions but is it possible to evaluate:

$$\int_{0}^{\sqrt{\pi}/2} \tan(x^2)dx$$

? (or with different limits?)

I couldn't find anything over the internet and I don't have any idea about the definite integral.

Any help is appreciated. Thanks!
