4∫tan(x^2)dx from 0 to √(π)/2


The Attempt at a Solution



I tried doing u-substitution, which didn't work, and also tried to look for a trig identity and wasn't able to find any relevant one.

Have you tried changing it to a ratio of sine and cosine and integrating by parts?
How about changing it to exponential form and tackling that?

in general trig functions of x^2 are pretty nasty.
If this is part of an exercise you should look to your notes about similar functions.
If not you may want to consider working your actual problem by another means.
