Вы ввели

   2*x   
sin   (x)

$$\sin^{2 x}{\left (x \right )}$$

Подробное решение

1. Не могу найти шаги в поиске этой производной.

   Но производная

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

Ответ:

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

Первая производная

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

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

Вторая производная

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

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

Третья производная

            /                               3                              /                    2   \        2             3                \
     2*x    |       /x*cos(x)              \      /x*cos(x)              \ |    2*cos(x)   x*cos (x)|   3*cos (x)   2*x*cos (x)   2*x*cos(x)|
2*sin   (x)*|-3 + 4*|-------- + log(sin(x))|  - 6*|-------- + log(sin(x))|*|x - -------- + ---------| - --------- + ----------- + ----------|
            |       \ sin(x)               /      \ sin(x)               / |     sin(x)        2    |       2            3          sin(x)  |
            \                                                              \                sin (x) /    sin (x)      sin (x)               /

$$2 \left(\frac{2 x \cos{\left (x \right )}}{\sin{\left (x \right )}} + \frac{2 x \cos^{3}{\left (x \right )}}{\sin^{3}{\left (x \right )}} + 4 \left(\frac{x \cos{\left (x \right )}}{\sin{\left (x \right )}} + \log{\left (\sin{\left (x \right )} \right )}\right)^{3} - 6 \left(\frac{x \cos{\left (x \right )}}{\sin{\left (x \right )}} + \log{\left (\sin{\left (x \right )} \right )}\right) \left(x + \frac{x \cos^{2}{\left (x \right )}}{\sin^{2}{\left (x \right )}} - \frac{2 \cos{\left (x \right )}}{\sin{\left (x \right )}}\right) - 3 - \frac{3 \cos^{2}{\left (x \right )}}{\sin^{2}{\left (x \right )}}\right) \sin^{2 x}{\left (x \right )}$$
