$$\frac{d}{d x} \sin{\left(\cos{\left(\sin{\left(x \right)} \right)} \right)}$$

Подробное решение

1. Заменим $u = \cos{\left(\sin{\left(x \right)} \right)}$.

2. Производная синуса есть косинус:

   $\frac{d}{d u} \sin{\left(u \right)} = \cos{\left(u \right)}$

3. Затем примените цепочку правил. Умножим на $\frac{d}{d x} \cos{\left(\sin{\left(x \right)} \right)}$:

   1. Заменим $u = \sin{\left(x \right)}$.

   2. Производная косинус есть минус синус:

      $\frac{d}{d u} \cos{\left(u \right)} = - \sin{\left(u \right)}$

   3. Затем примените цепочку правил. Умножим на $\frac{d}{d x} \sin{\left(x \right)}$:

      1. Производная синуса есть косинус:

         $\frac{d}{d x} \sin{\left(x \right)} = \cos{\left(x \right)}$

      В результате последовательности правил:

      $- \sin{\left(\sin{\left(x \right)} \right)} \cos{\left(x \right)}$

   В результате последовательности правил:

   $- \sin{\left(\sin{\left(x \right)} \right)} \cos{\left(x \right)} \cos{\left(\cos{\left(\sin{\left(x \right)} \right)} \right)}$

Ответ:

$- \sin{\left(\sin{\left(x \right)} \right)} \cos{\left(x \right)} \cos{\left(\cos{\left(\sin{\left(x \right)} \right)} \right)}$

Первая производная

-cos(x)*cos(cos(sin(x)))*sin(sin(x))

$$- \sin{\left(\sin{\left(x \right)} \right)} \cos{\left(x \right)} \cos{\left(\cos{\left(\sin{\left(x \right)} \right)} \right)}$$

Вторая производная

                                         2       2                               2                                
cos(cos(sin(x)))*sin(x)*sin(sin(x)) - cos (x)*sin (sin(x))*sin(cos(sin(x))) - cos (x)*cos(cos(sin(x)))*cos(sin(x))

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

Третья производная

/                                  2       3                               2                                        2                                                                                2                                            \       
\cos(cos(sin(x)))*sin(sin(x)) + cos (x)*sin (sin(x))*cos(cos(sin(x))) + cos (x)*cos(cos(sin(x)))*sin(sin(x)) + 3*sin (sin(x))*sin(x)*sin(cos(sin(x))) + 3*cos(cos(sin(x)))*cos(sin(x))*sin(x) - 3*cos (x)*cos(sin(x))*sin(cos(sin(x)))*sin(sin(x))/*cos(x)

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