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

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

E^x*(cos(x) - sin(x))

Detail solution

Apply the product rule:

$\frac{d}{d x} f{\left(x \right)} g{\left(x \right)} = f{\left(x \right)} \frac{d}{d x} g{\left(x \right)} + g{\left(x \right)} \frac{d}{d x} f{\left(x \right)}$

$f{\left(x \right)} = e^{x}$ ; to find $\frac{d}{d x} f{\left(x \right)}$ :
1. The derivative of $e^{x}$ is itself.
$g{\left(x \right)} = - \sin{\left(x \right)} + \cos{\left(x \right)}$ ; to find $\frac{d}{d x} g{\left(x \right)}$ :
1. Differentiate $- \sin{\left(x \right)} + \cos{\left(x \right)}$ term by term:
  1. The derivative of cosine is negative sine:
    
    $\frac{d}{d x} \cos{\left(x \right)} = - \sin{\left(x \right)}$
  2. The derivative of a constant times a function is the constant times the derivative of the function.
    1. The derivative of sine is cosine:
      
      $\frac{d}{d x} \sin{\left(x \right)} = \cos{\left(x \right)}$
    So, the result is: $- \cos{\left(x \right)}$
  The result is: $- \sin{\left(x \right)} - \cos{\left(x \right)}$
The result is: $\left(- \sin{\left(x \right)} - \cos{\left(x \right)}\right) e^{x} + \left(- \sin{\left(x \right)} + \cos{\left(x \right)}\right) e^{x}$
Now simplify:

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

The answer is:

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