Detail solution
  1. Apply the quotient rule, which is:

    and .

    To find :

    1. The derivative of sine is cosine:

    To find :

    1. The derivative of is itself.

    Now plug in to the quotient rule:

  2. Now simplify:


The answer is:

The graph
The first derivative [src]
        -x    -x       
cos(x)*e   - e  *sin(x)
$$- e^{- x} \sin{\left(x \right)} + e^{- x} \cos{\left(x \right)}$$
The second derivative [src]
           -x
-2*cos(x)*e  
$$- 2 e^{- x} \cos{\left(x \right)}$$
The third derivative [src]
                     -x
2*(cos(x) + sin(x))*e  
$$2 \left(\sin{\left(x \right)} + \cos{\left(x \right)}\right) e^{- x}$$
5-th derivative [src]
                      -x
4*(-cos(x) + sin(x))*e  
$$4 \left(\sin{\left(x \right)} - \cos{\left(x \right)}\right) e^{- x}$$
