$$x^{\operatorname{atan}{\left (3 x \right )}}$$

Подробное решение

1. Не могу найти шаги в поиске этой производной.

   Но производная

   $\left(\log{\left (\operatorname{atan}{\left (3 x \right )} \right )} + 1\right) \operatorname{atan}^{\operatorname{atan}{\left (3 x \right )}}{\left (3 x \right )}$

---

Ответ:

$\left(\log{\left (\operatorname{atan}{\left (3 x \right )} \right )} + 1\right) \operatorname{atan}^{\operatorname{atan}{\left (3 x \right )}}{\left (3 x \right )}$

Первая производная

 atan(3*x) /atan(3*x)   3*log(x)\
x         *|--------- + --------|
           |    x              2|
           \            1 + 9*x /

$$x^{\operatorname{atan}{\left (3 x \right )}} \left(\frac{3 \log{\left (x \right )}}{9 x^{2} + 1} + \frac{1}{x} \operatorname{atan}{\left (3 x \right )}\right)$$

Вторая производная

           /                      2                                         \
 atan(3*x) |/atan(3*x)   3*log(x)\    atan(3*x)        6         54*x*log(x)|
x         *||--------- + --------|  - --------- + ------------ - -----------|
           ||    x              2|         2        /       2\             2|
           |\            1 + 9*x /        x       x*\1 + 9*x /   /       2\ |
           \                                                     \1 + 9*x / /

$$x^{\operatorname{atan}{\left (3 x \right )}} \left(- \frac{54 x \log{\left (x \right )}}{\left(9 x^{2} + 1\right)^{2}} + \left(\frac{3 \log{\left (x \right )}}{9 x^{2} + 1} + \frac{1}{x} \operatorname{atan}{\left (3 x \right )}\right)^{2} + \frac{6}{x \left(9 x^{2} + 1\right)} - \frac{1}{x^{2}} \operatorname{atan}{\left (3 x \right )}\right)$$

           \                          \1 + 9*x /    \1 + 9*x /                                             \                           \1 + 9*x / /                  \1 + 9*x /   /

$$x^{\operatorname{atan}{\left (3 x \right )}} \left(\frac{1944 x^{2} \log{\left (x \right )}}{\left(9 x^{2} + 1\right)^{3}} + \left(\frac{3 \log{\left (x \right )}}{9 x^{2} + 1} + \frac{1}{x} \operatorname{atan}{\left (3 x \right )}\right)^{3} - 3 \left(\frac{3 \log{\left (x \right )}}{9 x^{2} + 1} + \frac{1}{x} \operatorname{atan}{\left (3 x \right )}\right) \left(\frac{54 x \log{\left (x \right )}}{\left(9 x^{2} + 1\right)^{2}} - \frac{6}{x \left(9 x^{2} + 1\right)} + \frac{1}{x^{2}} \operatorname{atan}{\left (3 x \right )}\right) - \frac{54 \log{\left (x \right )}}{\left(9 x^{2} + 1\right)^{2}} - \frac{162}{\left(9 x^{2} + 1\right)^{2}} - \frac{9}{x^{2} \left(9 x^{2} + 1\right)} + \frac{2}{x^{3}} \operatorname{atan}{\left (3 x \right )}\right)$$
