$$\left(\log{\left(x \right)} + 1\right)^{2}$$
(log(x) + 1)^2
Detail solution
  1. Let .

  2. Apply the power rule: goes to

  3. Then, apply the chain rule. Multiply by :

    1. Differentiate term by term:

      1. The derivative of is .

      2. The derivative of the constant is zero.

      The result is:

    The result of the chain rule is:

  4. Now simplify:


The answer is:

The graph
The first derivative [src]
2*(log(x) + 1)
--------------
      x       
$$\frac{2 \left(\log{\left(x \right)} + 1\right)}{x}$$
The second derivative [src]
-2*log(x)
---------
     2   
    x    
$$- \frac{2 \log{\left(x \right)}}{x^{2}}$$
The third derivative [src]
2*(-1 + 2*log(x))
-----------------
         3       
        x        
$$\frac{2 \left(2 \log{\left(x \right)} - 1\right)}{x^{3}}$$
