Problems with the derivative

  1. Dec 8, 2006 #1
    i would need some help to find the derivative of:

    [tex] y=log_{x} (x) [/tex] respect to x..:frown: the log is itself in base "x"...:rolleyes: to make the problem harder.

    Hint: [tex]\log_{b}x = \frac{\ln x}{\ln b}[/tex].

    Note that I changed the name of the base to b, rather than x.

    logx(x)=1. Therefore the derivative=0.
