# Mother of god, what is that?

Calculus Level 5

$\mathfrak{E} = \large \displaystyle \int_{1/2}^{1} \dfrac{2x \sin(2 \tan(x^2 ))}{\sin^2 (\tan(x^2)) \cos^2 (x^2)} \, dx$

Find $$\left \lfloor 1000 \mathfrak{E} \right \rfloor$$.

Details and assumptions:

After you have integrated and are ready to put in the limits of integration, of course by hand, then you may use a calculator to compute the final answer.
