Detail solution
  1. Let u=exu = e^{x}.

  2. The derivative of sine is cosine:

    ddusin(u)=cos(u)\frac{d}{d u} \sin{\left(u \right)} = \cos{\left(u \right)}

  3. Then, apply the chain rule. Multiply by ddxex\frac{d}{d x} e^{x}:

    1. The derivative of exe^{x} is itself.

    The result of the chain rule is:

    excos(ex)e^{x} \cos{\left(e^{x} \right)}

  4. Now simplify:

    excos(ex)e^{x} \cos{\left(e^{x} \right)}


The answer is:

excos(ex)e^{x} \cos{\left(e^{x} \right)}
