$$\sinh^{\tanh{\left (x \right )}}{\left (x \right )}$$

Подробное решение

1. Не могу найти шаги в поиске этой производной.

   Но производная

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

Ответ:

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

Первая производная

    tanh(x)    //        2   \                cosh(x)*tanh(x)\

               \                                  sinh(x)    /

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