x - + sin(log(x)) 2
x/2 + sin(log(x))
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:
Let .
The derivative of sine is cosine:
Then, apply the chain rule. Multiply by :
The derivative of is .
The result of the chain rule is:
The result is:
Now simplify:
The answer is:
1 cos(log(x)) - + ----------- 2 x
-(cos(log(x)) + sin(log(x))) ----------------------------- 2 x
3*sin(log(x)) + cos(log(x)) --------------------------- 3 x
