Don't know the steps in finding this derivative.
But the derivative is
The answer is:
The first derivative

2 / 2 / 2 \ \
cot (x) |cot (x)*\1 + tan (x)/ / 2 \ |
(tan(x)) *|--------------------- + \-2 - 2*cot (x)/*cot(x)*log(tan(x))|
\ tan(x) /
$$\left(\frac{\left(\tan^{2}{\left(x \right)} + 1\right) \cot^{2}{\left(x \right)}}{\tan{\left(x \right)}} + \left(- 2 \cot^{2}{\left(x \right)} - 2\right) \log{\left(\tan{\left(x \right)} \right)} \cot{\left(x \right)}\right) \tan^{\cot^{2}{\left(x \right)}}{\left(x \right)}$$
