Detail solution

Let $u = \sin{\left(4 x - 1 \right)}$ .
Apply the power rule: $u^{3}$ goes to $3 u^{2}$
Then, apply the chain rule. Multiply by $\frac{d}{d x} \sin{\left(4 x - 1 \right)}$ :
1. Let $u = 4 x - 1$ .
2. The derivative of sine is cosine:
  
  $\frac{d}{d u} \sin{\left(u \right)} = \cos{\left(u \right)}$
3. Then, apply the chain rule. Multiply by $\frac{d}{d x} \left(4 x - 1\right)$ :
  1. Differentiate $4 x - 1$ term by term:
    1. The derivative of a constant times a function is the constant times the derivative of the function.
      1. Apply the power rule: $x$ goes to $1$
      So, the result is: $4$
    2. The derivative of the constant $\left(-1\right) 1$ is zero.
    The result is: $4$
  The result of the chain rule is:
  
  $4 \cos{\left(4 x - 1 \right)}$
The result of the chain rule is:

$12 \sin^{2}{\left(4 x - 1 \right)} \cos{\left(4 x - 1 \right)}$
Now simplify:

$12 \sin^{2}{\left(4 x - 1 \right)} \cos{\left(4 x - 1 \right)}$

The answer is:

$12 \sin^{2}{\left(4 x - 1 \right)} \cos{\left(4 x - 1 \right)}$
