Detail solution
  1. Rewrite the function to be differentiated:

  2. Apply the quotient rule, which is:

    and .

    To find :

    1. Let .

    2. The derivative of sine is cosine:

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

      1. Differentiate term by term:

        1. 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:

        2. The derivative of the constant is zero.

        The result is:

      The result of the chain rule is:

    To find :

    1. Let .

    2. The derivative of cosine is negative sine:

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

      1. Differentiate term by term:

        1. 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:

        2. The derivative of the constant is zero.

        The result is:

      The result of the chain rule is:

    Now plug in to the quotient rule:

  3. Now simplify:


The answer is:

The graph
The first derivative [src]
         2/      pi\
3 + 3*tan |3*x - --|
          \      6 /
$$3 \tan^{2}{\left(3 x - \frac{\pi}{6} \right)} + 3$$
The second derivative [src]
    /       2/      pi\\    /      pi\
-18*|1 + cot |3*x + --||*cot|3*x + --|
    \        \      3 //    \      3 /
$$- 18 \left(\cot^{2}{\left(3 x + \frac{\pi}{3} \right)} + 1\right) \cot{\left(3 x + \frac{\pi}{3} \right)}$$
The third derivative [src]
   /       2/      pi\\ /         2/      pi\\
54*|1 + cot |3*x + --||*|1 + 3*cot |3*x + --||
   \        \      3 // \          \      3 //
