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 the constant is zero.
The result is:
The result of the chain rule is:
Now simplify:
The answer is:
/ 2 / 2\ / 2\\ 10*\- 10*x *sin\2 + 5*x / + cos\2 + 5*x //
/ / 2\ 2 / 2\\ -100*x*\3*sin\2 + 5*x / + 10*x *cos\2 + 5*x //
