Detail solution
-
Apply the quotient rule, which is:
and .
To find :
-
Apply the power rule: goes to
To find :
-
The derivative of is .
Now plug in to the quotient rule:
The answer is:
The first derivative

1 1
------ - -------
log(x) 2
log (x)
$$\frac{1}{\log{\left(x \right)}} - \frac{1}{\log{\left(x \right)}^{2}}$$
The second derivative

2
-1 + ------
log(x)
-----------
2
x*log (x)
$$\frac{-1 + \frac{2}{\log{\left(x \right)}}}{x \log{\left(x \right)}^{2}}$$
The third derivative

6
1 - -------
2
log (x)
-----------
2 2
x *log (x)
$$\frac{1 - \frac{6}{\log{\left(x \right)}^{2}}}{x^{2} \log{\left(x \right)}^{2}}$$
