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. Let .

      2. The derivative of sine is cosine:

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

        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:

        The result of the chain rule is:

      4. 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]
4*(sin(2*x) + 1)*cos(2*x)
$$4 \left(\sin{\left(2 x \right)} + 1\right) \cos{\left(2 x \right)}$$
The second derivative [src]
  /   2                               \
8*\cos (2*x) - (1 + sin(2*x))*sin(2*x)/
$$8 \left(- \left(\sin{\left(2 x \right)} + 1\right) \sin{\left(2 x \right)} + \cos^{2}{\left(2 x \right)}\right)$$
The third derivative [src]
-16*(1 + 4*sin(2*x))*cos(2*x)
$$- 16 \cdot \left(4 \sin{\left(2 x \right)} + 1\right) \cos{\left(2 x \right)}$$
