Detail solution
  1. Differentiate term by term:

    1. Differentiate term by term:

      1. Apply the product rule:

        ; to find :

        1. Differentiate term by term:

          1. The derivative of the constant is zero.

          2. Apply the power rule: goes to

          The result is:

        ; to find :

        1. The derivative of is .

        The result is:

      2. The derivative of a constant times a function is the constant times the derivative of the function.

        1. Apply the power rule: goes to

        So, the result is:

      The result is:

    2. The derivative of the constant is zero.

    The result is:

  2. Now simplify:


The answer is:

The first derivative [src]
     c1 + x         
-2 + ------ + log(x)
       x            
$$\log{\left(x \right)} - 2 + \frac{c_{1} + x}{x}$$
The second derivative [src]
    c1 + x
2 - ------
      x   
----------
    x     
$$\frac{2 - \frac{c_{1} + x}{x}}{x}$$
The third derivative [src]
     2*(c1 + x)
-3 + ----------
         x     
---------------
        2      
       x       
$$\frac{-3 + \frac{2 \left(c_{1} + x\right)}{x}}{x^{2}}$$
