Detail solution
  1. Differentiate term by term:

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

      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:

      So, the result is:

    2. The derivative of the constant is zero.

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

      1. Let .

      2. The derivative of cosine is negative sine:

      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 answer is:

The graph
The first derivative [src]
-12*sin(4*x) + 4*cos(2*x)
$$- 12 \sin{\left(4 x \right)} + 4 \cos{\left(2 x \right)}$$
The second derivative [src]
-8*(6*cos(4*x) + sin(2*x))
$$- 8 \left(\sin{\left(2 x \right)} + 6 \cos{\left(4 x \right)}\right)$$
3-th derivative [src]
16*(-cos(2*x) + 12*sin(4*x))
$$16 \cdot \left(12 \sin{\left(4 x \right)} - \cos{\left(2 x \right)}\right)$$
The third derivative [src]
16*(-cos(2*x) + 12*sin(4*x))
$$16 \cdot \left(12 \sin{\left(4 x \right)} - \cos{\left(2 x \right)}\right)$$
