/ 2\ \3 / (sin(x))
/ / 2\\ d | \3 /| --\(sin(x)) / dx
Let .
Apply the power rule: goes to
Then, apply the chain rule. Multiply by :
The derivative of sine is cosine:
The result of the chain rule is:
Now simplify:
The answer is:
/ 2\ \3 / 9*(sin(x)) *cos(x) --------------------- sin(x)
7 / 2 2 \ 9*sin (x)*\- sin (x) + 8*cos (x)/
6 / 2 2 \ 9*sin (x)*\- 25*sin (x) + 56*cos (x)/*cos(x)
