Transform

Detail solution

Let $u = \cos{\left(\sin{\left(x \right)} \right)}$ .
Apply the power rule: $u^{2}$ goes to $2 u$
Then, apply the chain rule. Multiply by $\frac{d}{d x} \cos{\left(\sin{\left(x \right)} \right)}$ :
1. Let $u = \sin{\left(x \right)}$ .
2. The derivative of cosine is negative sine:
  
  $\frac{d}{d u} \cos{\left(u \right)} = - \sin{\left(u \right)}$
3. Then, apply the chain rule. Multiply by $\frac{d}{d x} \sin{\left(x \right)}$ :
  1. The derivative of sine is cosine:
    
    $\frac{d}{d x} \sin{\left(x \right)} = \cos{\left(x \right)}$
  The result of the chain rule is:
  
  $- \sin{\left(\sin{\left(x \right)} \right)} \cos{\left(x \right)}$
The result of the chain rule is:

$- 2 \sin{\left(\sin{\left(x \right)} \right)} \cos{\left(x \right)} \cos{\left(\sin{\left(x \right)} \right)}$
Now simplify:

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

The answer is:

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

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

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