(-(((x/lnx)-xln(-lnx)))/x... --- can anyone bring up to date me what the derivative of this function is? appreciation?
Question: y = (-(((x/lnx)-xln(-lnx)))/x)+(1/...
Answers:
y = (-(((x/lnx)
-xln(-lnx)))/x)
=(-1/lnx+ln(ln(1/x))
y'=(1/(x*(lnx)^2)
-1/(x(ln(1/x))
=1/(x){1/(lnx)^2-1/ln(1/x))}
[x is not equal to 0]
{using the chain rule}
i hope that this help
