Подробное решение

1. Не могу найти шаги в поиске этой производной.

   Но производная

   $x^{x} \left(\log{\left (x \right )} + 1\right)$

Ответ:

$x^{x} \left(\log{\left (x \right )} + 1\right)$

Первая производная

        /  /       2   \              \
   x    |x*\1 + tan (x)/              |
tan (x)*|--------------- + log(tan(x))|
        \     tan(x)                  /

$$\left(\frac{x \left(\tan^{2}{\left (x \right )} + 1\right)}{\tan{\left (x \right )}} + \log{\left (\tan{\left (x \right )} \right )}\right) \tan^{x}{\left (x \right )}$$

Вторая производная

        /                               2                                                 \

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