Detail solution
  1. 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. The derivative of sine is cosine:

      The result of the chain rule is:

    So, the result is:


The answer is:

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