Transform

Detail solution

Differentiate $x^{3} \sin{\left(5 x \right)} + \log{\left(x \right)}^{2}$ term by term:
1. Apply the product rule:
  
  $\frac{d}{d x} f{\left(x \right)} g{\left(x \right)} = f{\left(x \right)} \frac{d}{d x} g{\left(x \right)} + g{\left(x \right)} \frac{d}{d x} f{\left(x \right)}$
  
  $f{\left(x \right)} = x^{3}$ ; to find $\frac{d}{d x} f{\left(x \right)}$ :
  1. Apply the power rule: $x^{3}$ goes to $3 x^{2}$
  $g{\left(x \right)} = \sin{\left(5 x \right)}$ ; to find $\frac{d}{d x} g{\left(x \right)}$ :
  1. Let $u = 5 x$ .
  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 $\frac{d}{d x} 5 x$ :
    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: $5$
    The result of the chain rule is:
    
    $5 \cos{\left(5 x \right)}$
  The result is: $5 x^{3} \cos{\left(5 x \right)} + 3 x^{2} \sin{\left(5 x \right)}$
2. Let $u = \log{\left(x \right)}$ .
3. Apply the power rule: $u^{2}$ goes to $2 u$
4. Then, apply the chain rule. Multiply by $\frac{d}{d x} \log{\left(x \right)}$ :
  1. The derivative of $\log{\left(x \right)}$ is $\frac{1}{x}$ .
  The result of the chain rule is:
  
  $\frac{2 \log{\left(x \right)}}{x}$
The result is: $5 x^{3} \cos{\left(5 x \right)} + 3 x^{2} \sin{\left(5 x \right)} + \frac{2 \log{\left(x \right)}}{x}$
Now simplify:

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

The answer is:

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