Apply the quotient rule, which is:
and .
To find :
Differentiate term by term:
The derivative of the constant is zero.
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:
To find :
The derivative of is .
Now plug in to the quotient rule:
Now simplify:
The answer is:
1 2 - x - ------ - --------- log(x) 2 x*log (x)
/ 2 \ |1 + ------|*(-2 + x) \ log(x)/ 2 - --------------------- x ------------------------- 2 x*log (x)
/ 3 3 \ 2*(-2 + x)*|1 + ------ + -------| | log(x) 2 | 6 \ log (x)/ -3 - ------ + --------------------------------- log(x) x ----------------------------------------------- 2 2 x *log (x)
