3 2 x - 3*x --------- 3 (x - 1)
/ 3 2\ d |x - 3*x | --|---------| dx| 3| \ (x - 1) /
Apply the quotient rule, which is:
and .
To find :
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:
To find :
Let .
Apply the power rule: goes to
Then, apply the chain rule. Multiply by :
Differentiate term by term:
The derivative of the constant is zero.
Apply the power rule: goes to
The result is:
The result of the chain rule is:
Now plug in to the quotient rule:
Now simplify:
The answer is:
2 / 3 2\ -6*x + 3*x 3*\x - 3*x / ----------- - ------------- 3 4 (x - 1) (x - 1)
