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