Transform

Detail solution

Let $u = \sin{\left(6 x \right)} + 1$ .
Apply the power rule: $\sqrt[4]{u}$ goes to $\frac{1}{4 u^{\frac{3}{4}}}$
Then, apply the chain rule. Multiply by $\frac{d}{d x} \left(\sin{\left(6 x \right)} + 1\right)$ :
1. Differentiate $\sin{\left(6 x \right)} + 1$ term by term:
  1. The derivative of the constant $1$ is zero.
  2. Let $u = 6 x$ .
  3. The derivative of sine is cosine:
    
    $\frac{d}{d u} \sin{\left(u \right)} = \cos{\left(u \right)}$
  4. Then, apply the chain rule. Multiply by $\frac{d}{d x} 6 x$ :
    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: $6$
    The result of the chain rule is:
    
    $6 \cos{\left(6 x \right)}$
  The result is: $6 \cos{\left(6 x \right)}$
The result of the chain rule is:

$\frac{3 \cos{\left(6 x \right)}}{2 \left(\sin{\left(6 x \right)} + 1\right)^{\frac{3}{4}}}$

The answer is:

$\frac{3 \cos{\left(6 x \right)}}{2 \left(\sin{\left(6 x \right)} + 1\right)^{\frac{3}{4}}}$
