Transform

Detail solution

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

$- 4 e^{4 \cos{\left(x - 1 \right)}} \sin{\left(x - 1 \right)}$
Now simplify:

$- 4 e^{4 \cos{\left(x - 1 \right)}} \sin{\left(x - 1 \right)}$

The answer is:

- 4 e^{4 \cos{\left(x - 1 \right)}} \sin{\left(x - 1 \right)}
