Transform

Detail solution

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

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

$- e^{\frac{\cos{\left(2 x \right)}}{2} + \frac{1}{2}} \sin{\left(2 x \right)}$

The answer is:

$- e^{\frac{\cos{\left(2 x \right)}}{2} + \frac{1}{2}} \sin{\left(2 x \right)}$

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

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

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