Question

Is this correct? Derivatives of log. functs.

Answer 1

\[f(u)=\frac{ u }{ 1+lnu }=\frac{ (1+lnu)\times1-\frac{ 1 }{ u }\times u }{ (1+lnu)^2 }=\frac{ lnu }{ (1+lnu)^2 }\]

Answer 2

yaaa it's prolly good :d

Answer 3

okay, thanks again :D

Answer 4

Just finished with implicit derivatives section, so I'm on the logs section now
