        _______
x - 2*\/ x - 2 
$$x - 2 \sqrt{x - 2}$$
x - 2*sqrt(x - 2)
Detail solution
  1. Differentiate term by term:

    1. Apply the power rule: goes to

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

      1. Let .

      2. Apply the power rule: goes to

      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:

      So, the result is:

    The result is:

  2. Now simplify:


The answer is:

The first derivative [src]
        1    
1 - ---------
      _______
    \/ x - 2 
$$1 - \frac{1}{\sqrt{x - 2}}$$
The second derivative [src]

          3/2
2*(-2 + x)   
$$\frac{1}{2 \left(x - 2\right)^{\frac{3}{2}}}$$
The third derivative [src]
     -3      
-------------
          5/2
4*(-2 + x)   
$$- \frac{3}{4 \left(x - 2\right)^{\frac{5}{2}}}$$
