Detail solution
  1. Let u=sin(x)u = \sin{\left(x \right)}.

  2. Apply the power rule: u5u^{5} goes to 5u45 u^{4}

  3. Then, apply the chain rule. Multiply by ddxsin(x)\frac{d}{d x} \sin{\left(x \right)}:

    1. The derivative of sine is cosine:

      ddxsin(x)=cos(x)\frac{d}{d x} \sin{\left(x \right)} = \cos{\left(x \right)}

    The result of the chain rule is:

    5sin4(x)cos(x)5 \sin^{4}{\left(x \right)} \cos{\left(x \right)}


The answer is:

5sin4(x)cos(x)5 \sin^{4}{\left(x \right)} \cos{\left(x \right)}
