Transform

Detail solution

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

$- \left(2 e^{\cos{\left(x \right)}} + 4\right) e^{\cos{\left(x \right)}} \sin{\left(x \right)}$
Now simplify:

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

The answer is:

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

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

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

The third derivative [src]

  /       2    /     cos(x)\        2     cos(x)     /     cos(x)\                    cos(x)    cos(x)\  cos(x)

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