Derivative of y=sin^23xcos^32x

1. Apply the product rule:

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

   $f{\left(x \right)} = \sin^{23}{\left(x \right)}$; to find $\frac{d}{d x} f{\left(x \right)}$:

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

   2. Apply the power rule: $u^{23}$ goes to $23 u^{22}$

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

      1. The derivative of sine is cosine:

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

      The result of the chain rule is:

      $$23 \sin^{22}{\left(x \right)} \cos{\left(x \right)}$$

   $g{\left(x \right)} = \cos^{32}{\left(x \right)}$; to find $\frac{d}{d x} g{\left(x \right)}$:

   1. Let $u = \cos{\left(x \right)}$.

   2. Apply the power rule: $u^{32}$ goes to $32 u^{31}$

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

      1. The derivative of cosine is negative sine:

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

      The result of the chain rule is:

      $$- 32 \sin{\left(x \right)} \cos^{31}{\left(x \right)}$$

   The result is: $- 32 \sin^{24}{\left(x \right)} \cos^{31}{\left(x \right)} + 23 \sin^{22}{\left(x \right)} \cos^{33}{\left(x \right)}$

2. Now simplify:

   $$\left(23 - 55 \sin^{2}{\left(x \right)}\right) \sin^{22}{\left(x \right)} \cos^{31}{\left(x \right)}$$

The answer is:
