The solution

You have entered [src]
log(x + 1) + 1
$$\log{\left(x + 1 \right)} + 1$$
log(x + 1) + 1
Detail solution
  1. Differentiate term by term:

    1. Let .

    2. The derivative of is .

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

      1. Differentiate term by term:

        1. Apply the power rule: goes to

        2. The derivative of the constant is zero.

        The result is:

      The result of the chain rule is:

    4. The derivative of the constant is zero.

    The result is:

  2. Now simplify:


The answer is:

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