/ 2 \ log\x + x/ ----------- log(2)
log(x^2 + x)/log(2)
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 :
Differentiate term by term:
Apply the power rule: goes to
Apply the power rule: goes to
The result is:
The result of the chain rule is:
So, the result is:
Now simplify:
The answer is:
1 + 2*x --------------- / 2 \ \x + x/*log(2)
2 (1 + 2*x) 2 - ---------- x*(1 + x) ---------------- x*(1 + x)*log(2)
/ 2\ | (1 + 2*x) | -2*(1 + 2*x)*|3 - ----------| \ x*(1 + x) / ----------------------------- 2 2 x *(1 + x) *log(2)
