Let .
The derivative of sine is cosine:
Then, apply the chain rule. Multiply by :
Differentiate term by term:
The derivative of a constant times a function is the constant times the derivative of the function.
Apply the power rule: goes to
So, the result is:
The derivative of a constant times a function is the constant times the derivative of the function.
Apply the power rule: goes to
So, the result is:
The result is:
The result of the chain rule is:
Now simplify:
The answer is:
/ 2\ / 3\ \5 + 9*x /*cos\5*x + 3*x /
2 / 2\ / / 2\\ / / 2\\ - \5 + 9*x / *sin\x*\5 + 3*x // + 18*x*cos\x*\5 + 3*x //
3 / / 2\\ / 2\ / / 2\\ / 2\ / / 2\\ 18*cos\x*\5 + 3*x // - \5 + 9*x / *cos\x*\5 + 3*x // - 54*x*\5 + 9*x /*sin\x*\5 + 3*x //
