Detail solution
  1. Let .

  2. Apply the power rule: goes to

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

    1. The derivative of sine is cosine:

    The result of the chain rule is:


The answer is:

The graph
The first derivative [src]
     2          
3*sin (x)*cos(x)
$$3 \sin^{2}{\left(x \right)} \cos{\left(x \right)}$$
The second derivative [src]
  /     2           2   \       
3*\- sin (x) + 2*cos (x)/*sin(x)
$$3 \left(- \sin^{2}{\left(x \right)} + 2 \cos^{2}{\left(x \right)}\right) \sin{\left(x \right)}$$
The third derivative [src]
  /       2           2   \       
3*\- 7*sin (x) + 2*cos (x)/*cos(x)
$$3 \left(- 7 \sin^{2}{\left(x \right)} + 2 \cos^{2}{\left(x \right)}\right) \cos{\left(x \right)}$$
