log(sin(5*x))
d --(log(sin(5*x))) dx
Let .
The derivative of is .
Then, apply the chain rule. Multiply by :
Let .
The derivative of sine is cosine:
Then, apply the chain rule. Multiply by :
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 of the chain rule is:
The result of the chain rule is:
Now simplify:
The answer is:
5*cos(5*x) ---------- sin(5*x)
/ 2 \ | cos (5*x)| -25*|1 + ---------| | 2 | \ sin (5*x)/
/ 2 \ | cos (5*x)| 250*|1 + ---------|*cos(5*x) | 2 | \ sin (5*x)/ ---------------------------- sin(5*x)
