# Just a small twist

Calculus Level 4

$\large{\int^{\frac{\pi}{4}}_{0} (\tan^{2016} (x)+\tan^{2014} (x))d(x-\frac{\lfloor x \rfloor}{1!}+\frac{\lfloor x \rfloor^{2}}{2!}-\frac{\lfloor x \rfloor^3}{3!}+\ldots)}$

If the value of the integral above equals to $$\frac ab$$ for coprime positive integers, find the value of $$a+b$$.
