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]
      21          
22*sin  (x)*cos(x)
$$22 \sin^{21}{\left(x \right)} \cos{\left(x \right)}$$
The second derivative [src]
      20    /     2            2   \
22*sin  (x)*\- sin (x) + 21*cos (x)/
$$22 \left(- \sin^{2}{\left(x \right)} + 21 \cos^{2}{\left(x \right)}\right) \sin^{20}{\left(x \right)}$$
The third derivative [src]
      19    /        2             2   \       
88*sin  (x)*\- 16*sin (x) + 105*cos (x)/*cos(x)
$$88 \left(- 16 \sin^{2}{\left(x \right)} + 105 \cos^{2}{\left(x \right)}\right) \sin^{19}{\left(x \right)} \cos{\left(x \right)}$$
