Вы ввели

       cos(x)
(x + 2)      

$$\left(x + 2\right)^{\cos{\left (x \right )}}$$

Подробное решение

1. Не могу найти шаги в поиске этой производной.

   Но производная

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

Ответ:

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

Первая производная

       cos(x) /cos(x)                    \
(x + 2)      *|------ - log(x + 2)*sin(x)|
              \x + 2                     /

$$\left(x + 2\right)^{\cos{\left (x \right )}} \left(- \log{\left (x + 2 \right )} \sin{\left (x \right )} + \frac{\cos{\left (x \right )}}{x + 2}\right)$$

Вторая производная

              /                            2                                          \
       cos(x) |/                    cos(x)\     cos(x)                        2*sin(x)|
(2 + x)      *||log(2 + x)*sin(x) - ------|  - -------- - cos(x)*log(2 + x) - --------|
              |\                    2 + x /           2                        2 + x  |
              \                                (2 + x)                                /

$$\left(x + 2\right)^{\cos{\left (x \right )}} \left(\left(\log{\left (x + 2 \right )} \sin{\left (x \right )} - \frac{\cos{\left (x \right )}}{x + 2}\right)^{2} - \log{\left (x + 2 \right )} \cos{\left (x \right )} - \frac{2 \sin{\left (x \right )}}{x + 2} - \frac{\cos{\left (x \right )}}{\left(x + 2\right)^{2}}\right)$$

Третья производная

              |  \                    2 + x /                         2 + x            3          2     \                    2 + x / |       2                        2 + x  ||
