Detail solution

Let $u = \sec{\left(x^{3} \right)}$ .
Apply the power rule: $u^{4}$ goes to $4 u^{3}$
Then, apply the chain rule. Multiply by $\frac{d}{d x} \sec{\left(x^{3} \right)}$ :
1. Rewrite the function to be differentiated:
  
  $\sec{\left(x^{3} \right)} = \frac{1}{\cos{\left(x^{3} \right)}}$
2. Let $u = \cos{\left(x^{3} \right)}$ .
3. Apply the power rule: $\frac{1}{u}$ goes to $- \frac{1}{u^{2}}$
4. Then, apply the chain rule. Multiply by $\frac{d}{d x} \cos{\left(x^{3} \right)}$ :
  1. Let $u = x^{3}$ .
  2. The derivative of cosine is negative sine:
    
    $\frac{d}{d u} \cos{\left(u \right)} = - \sin{\left(u \right)}$
  3. Then, apply the chain rule. Multiply by $\frac{d}{d x} x^{3}$ :
    1. Apply the power rule: $x^{3}$ goes to $3 x^{2}$
    The result of the chain rule is:
    
    $- 3 x^{2} \sin{\left(x^{3} \right)}$
  The result of the chain rule is:
  
  $\frac{3 x^{2} \sin{\left(x^{3} \right)}}{\cos^{2}{\left(x^{3} \right)}}$
The result of the chain rule is:

$\frac{12 x^{2} \sin{\left(x^{3} \right)} \sec^{3}{\left(x^{3} \right)}}{\cos^{2}{\left(x^{3} \right)}}$
Now simplify:

$\frac{12 x^{2} \sin{\left(x^{3} \right)}}{\cos^{5}{\left(x^{3} \right)}}$

The answer is:

$\frac{12 x^{2} \sin{\left(x^{3} \right)}}{\cos^{5}{\left(x^{3} \right)}}$
