Transform

Detail solution

Let $u = \log{\left(x^{3} + 1 \right)}$ .
The derivative of sine is cosine:

$\frac{d}{d u} \sin{\left(u \right)} = \cos{\left(u \right)}$
Then, apply the chain rule. Multiply by $\frac{d}{d x} \log{\left(x^{3} + 1 \right)}$ :
1. Let $u = x^{3} + 1$ .
2. The derivative of $\log{\left(u \right)}$ is $\frac{1}{u}$ .
3. Then, apply the chain rule. Multiply by $\frac{d}{d x} \left(x^{3} + 1\right)$ :
  1. Differentiate $x^{3} + 1$ term by term:
    1. Apply the power rule: $x^{3}$ goes to $3 x^{2}$
    2. The derivative of the constant $1$ is zero.
    The result is: $3 x^{2}$
  The result of the chain rule is:
  
  $\frac{3 x^{2}}{x^{3} + 1}$
The result of the chain rule is:

$\frac{3 x^{2} \cos{\left(\log{\left(x^{3} + 1 \right)} \right)}}{x^{3} + 1}$
Now simplify:

$\frac{3 x^{2} \cos{\left(\log{\left(x^{3} + 1 \right)} \right)}}{x^{3} + 1}$

The answer is:

$\frac{3 x^{2} \cos{\left(\log{\left(x^{3} + 1 \right)} \right)}}{x^{3} + 1}$
