/1 1\ 3*log|-- - -| | 1 x| \x /
3*log(1/(x^1) - 1/x)
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:
Let .
Apply the power rule: goes to
Then, apply the chain rule. Multiply by :
Apply the power rule: goes to
The result of the chain rule is:
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 result of the chain rule is:
So, the result is:
The answer is:
/1 1 \ 3*|-- - ---| | 2 x*x| \x / ------------ 1 1 -- - - 1 x x
