Подробное решение
Не могу найти шаги в поиске этой производной.
Но производная
Ответ:
x /x*cos(x) \
sin (x)*|-------- + log(sin(x))|
\ sin(x) /
$$\left(\frac{x \cos{\left (x \right )}}{\sin{\left (x \right )}} + \log{\left (\sin{\left (x \right )} \right )}\right) \sin^{x}{\left (x \right )}$$
/ 2 2 \
x |/x*cos(x) \ 2*cos(x) x*cos (x)|
sin (x)*||-------- + log(sin(x))| - x + -------- - ---------|
|\ sin(x) / sin(x) 2 |
\ sin (x) /
$$\left(- x - \frac{x \cos^{2}{\left (x \right )}}{\sin^{2}{\left (x \right )}} + \left(\frac{x \cos{\left (x \right )}}{\sin{\left (x \right )}} + \log{\left (\sin{\left (x \right )} \right )}\right)^{2} + \frac{2 \cos{\left (x \right )}}{\sin{\left (x \right )}}\right) \sin^{x}{\left (x \right )}$$
