sin(x)^9
Detail solution
  1. Let u=sin(x)u = \sin{\left(x \right)}.

  2. Apply the power rule: u9u^{9} goes to 9u89 u^{8}

  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:

    9sin8(x)cos(x)9 \sin^{8}{\left(x \right)} \cos{\left(x \right)}


The answer is:

9sin8(x)cos(x)9 \sin^{8}{\left(x \right)} \cos{\left(x \right)}
