/ 2 \ log\x + 2*x + 2/
log(x^2 + 2*x + 2)
Let .
The derivative of is .
Then, apply the chain rule. Multiply by :
Differentiate term by term:
Differentiate term by term:
Apply the power rule: goes to
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 derivative of the constant is zero.
The result is:
The result of the chain rule is:
Now simplify:
The answer is:
2 + 2*x ------------ 2 x + 2*x + 2
/ 2 \ | 2*(1 + x) | 2*|1 - ------------| | 2 | \ 2 + x + 2*x/ -------------------- 2 2 + x + 2*x
